CARLO GAVAZZI
A u t o m a t i o n C o m p o n e n t s
Announces new Solid State Contactors and reversing contactors.


Carlo Gavazzi has announced the launch of the REC Series of 3-phase Solid State Contactors and Reversing Contactors. The REC Series is twenty times more durable than equivalent mechanical contactors and succeeds in handling high frequency switching. The REC Series is comprised of a 3-pole non-reversing version with three switched phases or a 3-pole non-reversing and reversing versions with two switched phases. The first solution eliminates direct connection from the power supply to motor, while the second one maintains the same performance level while providing relevant cost reduction. The REC is mechanically compatible with Carlo Gavazzi’s CGT-22 line of bimetallic overload modules, by means of a plastic adapter.
In addition to competitive pricing, the REC Series assures substantial savings, as it
reduces system downtime and maintenance costs. The solid state contactors are provided
with a 1,600 Vp blocking voltage option that enhances their surge current ratings.
The REC Series is cUL listed as a motor starter and complies with the NMFT/NMFT7
requirements. The main technical features include:


• REC2 / REC3 – direct starting of
3-phase motors up to 5Hp at 480VAC
• REC2R – direct starting and reversing of
3-phase motors up to 5Hp at 480VAC
• Full load rating at 40°C / 104°F
• Instant-on switching
• Rated operational voltage up to 600VAC
• AC or DC control options
• Mechanical contactor resemblance with
covered heat sink
• Connects to CGT-22 overload module
• Control status LED indication
• DIN-rail or panel mounting
• cULus listed, CE and RoHS compliant


REC is an electronic contactor intended to replace the traditional mechanical counterpart used to switch three phase motors. The range includes 2 and 3 phase switching versions up to 4kW and 600Vrms.
Options with high surge current and I²t for fusing purposes are also available. The relay switches instantaneously upon application of the control voltage to emulate mechanical relay operation. A covered heatsink resolves any issues with regards to cables running close to the heatsink and eliminates the need for protective earth cabling. The product can be mounted on DIN-rail or on a panel. Note:
Specifications stated at 25°C unless specified.


The solid state contactors are available from Carlo Gavazzi’s North American authorized stocking distributor Anderson-Bolds.

TRC High Power GFCI's ~ Ground Fault Circuit Interrupter

Anderson-Bolds and TRC

Avoiding electrical accidents and equipment damage are keys to reducing liability and increasing productivity. Minimum ground fault protection can be incorporated into the main power disconnect device and could be considered adequate for the entire system. However, in such a design, any downstream ground fault could trip the main protective device resulting in a complete substation power outage. The NEC’s purpose, in its own words, is “the practical safeguarding of persons and property…but not necessarily efficient, convenient, or …for good service…” (Article 90.1A, B). In other words, system reliability is left to common sense and good engineering design practices. For this reason ground fault protection of the circuit may be highly desirable and recommended for reliable and continuous operation.

TRC engineers designed the HD-PRO models specifically for high current, rugged environments and these models are field-proven in all kinds of tough applications. The entire HD-PRO family (120V/30A to 600V/80A) is designed to trip within 25 milliseconds after ground fault detection at an adjustable selected trip level of 6, 10 or 30 mA.

ARC WELDING APPLICATIONS

Arc welding is described as using a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point. The process of arc welding is widely used because of its low capital and running costs.

Arc welding can use either direct (DC) or alternating (AC) current as the power source to create the arc. The arc process needs a large amount of current, up to 500A, but at a relatively low arc voltage; 10 to 40V, with a typical high voltage main power supply, and 230 to 400V, that must be reduced. In all manual arc welding operations the main risk is electric shock, most likely from contact with bare live parts of the welding circuit. Appropriate protective clothing and ground fault protection is the first line of defense in the event of an electrical hazard from stray currents. Bad equipment can be replaced in a short time; however, fire and serious injury or death caused by a ground fault could shut down a facility for several days or weeks.

How to avoid electrical shock: Always use a local ground fault circuit interrupter (GFCI) with welding equipment and, prior to use, always test the GFCI for proper operation. Use well-insulated electrode holders and cables. Make sure welding cables are dry and free of grease and oil. Keep welding cables away from power supply cables. Wear dry hole-free gloves, clothing should also be dry. Insulate welder from the ground by using dry insulation such as rubber mat or dry wood. Ground frames of welding units. Never change electrodes with bare hands or wet gloves.

Fortunately, ground fault protection is easy to apply if you understand the basics. Simply put, a ground fault occurs when electrical current finds a bridge to ground via worn insulations, conductive dusts, water or other “soft grounds”, instead of the normal path back to its source. More than 80% of short circuits in equipment are ground faults, and 90% of these events are due to insulation deterioration on wires and cables. In cases where workers accidentally bridge power and ground, current in the mA range can send their heart into ventricular fibrillation.

A GFCI functions by measuring the outgoing amperage to a piece of equipment and comparing it against the return amperage. If a difference (leak) of >5 milliamps occurs (or set higher for certain equipment), the GFCI stops the flow of electricity to protect equipment and workers from potential electrocution.

Avoiding electrical accidents and equipment damage are keys to reducing liability and increasing productivity. Minimum ground fault protection can be incorporated into the main power disconnect device and could be considered adequate for the entire system. In such a design, however, any downstream ground fault could trip the main protective device resulting in a complete substation power outage. The NEC’s purpose, in its own words, is “the practical safeguarding of persons and property…but not necessarily efficient, convenient, or …for good service…” (Article 90.1A, B). In other words, system reliability is left to common sense and good engineering design practices. For this reason ground fault protection of the circuit may be highly desirable and recommended for reliable and continuous operation.

Also, in order to comply with OSHA Regulations’ recent change, “construction-like” work using temporary power arrangements which takes place in the nation’s manufacturing plants, refineries, processing facilities and other locations, must be done with workers using GFCI protected equipment.

Pressure Washer

Industrial pressure washers are powerful tools used for washing buildings, bricks, floors, storefronts, parking lots, dumpsters,

bus fleets, machinery, farm equipment, engines and more. From industrial power plants to disaster clean-up you will find all

types of high end power pressure washers being used for many industrial applications. These machines are sophisticated

and built with more durable pumps and components then the residential units. They are also used in extreme environmental

conditions requiring more power; thereby posing a greater safety risk to individuals if not used properly.

A “Ground Fault” is a dangerous electrical condition where current flows unintentionally

between a live conductor and ground. A severe or fatal electric shock can occur when a user

touches the pressure washer if the machine is ungrounded. This could happen if the power

cord to extension cord connections become wet or a fault exists within the pressure washer’s

sophisticated electrical system. GFCI’s prevent possible electrocution and equipment damage

due to electrical malfunction. Once the GFCI trips, the power is interrupted, stopping the

pressure washer power and making it electrically safe for people and preventing costly

equipment damage.

The 1987 edition of the National Electrical Code requires that pressure washers be protected by ground fault interrupters to

prevent electrocutions. Also, the Underwriters Laboratories revised UL1776 requires the use of GFCI’s for all UL listed

pressure washers effective as of May 6, 2000.

Avoiding electrical accidents and equipment damage are keys to reducing liability and increasing productivity. Guidelines for

electrical safety are:

Always use and test the ground fault circuit interrupter (circuit breaker or outlet) before using a pressure washer.

Always plug a properly grounded pressure washer into a properly grounded receptacle.

Never remove the grounding prong from the pressure washer’s power cord plug or from the extension cord.

Always have a qualified electrician check the pressure washer for electrical problems after it has tripped a circuit

breaker.

HOISTS

Moving large heavy loads is crucial to today's manufacturing and construction industries. Hoists are one of the top

productivity-enhancing tools found almost anywhere goods are regularly moved, worked on and/or mounted into an

assembly. Some hoists use chains, ropes, or cable, but regardless, most use A/C motors. A burnt out motor can be replaced

in a short time, but fire or serious injury or death caused by a ground fault could shut down a facility for several days or

weeks. Fortunately, ground fault protection is easy to apply if you understand the basics.

A ground fault occurs when electrical current finds a bridge to ground via worn insulations,

conductive dusts, water or other “soft grounds” instead of the normal path back to its source.

More than 80% of short circuits in equipment are ground faults, and 90% of these events are

due to insulation deterioration on wires and cables. In cases where workers accidentally bridge

power and ground, current in the mA range can send their hearts into ventricular fibrillation.

A GFCI (Ground Fault Circuit Interrupter) functions by measuring the outgoing amperage to a

piece of equipment and comparing it against the return amperage. If a difference (leak) of > 5

milliamps occurs (or set higher for certain equipment), the GFCI stops the flow of electricity to

protect equipment and workers from potential electrocution.

Avoiding electrical accidents and equipment damage are keys to reducing liability and increasing productivity. Minimum

ground fault protection can be incorporated into the main power disconnect device and could be considered adequate for the

entire system. In such a design, however, any downstream ground fault could trip the main protective device resulting in a

complete substation power outage. The NEC’s purpose, in its own words, is “the practical safeguarding of persons and

property…but not necessarily efficient, convenient, or …for good service…” (Article 90.1A, B). In other words, system

reliability is left to common sense and good engineering design practices. For this reason ground fault protection of the

circuit may be highly desirable and recommended for reliable and continuous operation.

Guidelines for electrical safety are:

Know where the GFCI is located in the hoist power system. If there is not a GFCI installed, have one installed local

to the hoist to confirm you have protection.

Always test the GFCI before using the hoist.

Always have a qualified electrician check the hoist for electrical problems after it has tripped a GFCI.

CONVEYORS

Conveyors are commonly found in factories, industrial facilities, warehouses, distribution centers and in a large number of

manufacturing workplaces. A top productivity-enhancing tool, conveyor systems are used in almost every manufacturing

environment where goods are regularly moved from one location to another. Because of this, conveyor injuries in the U.S.

may cost employers millions of dollars each year; however, with the right processes, design and safety considerations,

employers can reduce cost and liability.

Conveyors are often driven by variable speed electric motors integrated (hardwired) into

complex power systems. As with any electronic equipment they are subject to failure for many

possible reasons. To protect people who use electrically-powered conveyors, each conveyor

must be equipped with a “Ground Fault Circuit Interrupter” (GFCI) preferably localized at the

GFCI’s prevent possible electrocution and equipment damage due to electrical malfunction.

Once the GFCI trips, the power is interrupted, stopping the conveyor system and making it

electrically safe for people and preventing costly equipment damage.

Ground fault protection is an important consideration for virtually all electrical equipment. A Ground Fault is a dangerous

electrical condition where current flows unintentionally between a live conductor and ground. This could happen if the power

unit or power cables become damaged, wet or a fault exists within the conveyor’ssophisticated electrical system. Avoiding

electrical accidents and equipment damage are keys to reducing liability and increasing productivity.

Guidelines for electrical safety are:

Know where the ground fault circuit interrupter is located in the conveyor power system. If there is not a GFCI

installed, report this to your safety officer.

Always test the ground fault circuit interrupter before using the conveyor.

Always have a qualified electrician check the conveyor for electrical problems after it has tripped a groundfault

circuit interrupter.

HD Pro GFCI's

TRC engineers designed the HD-PRO models specifically for high current, rugged environments and these models are field-proven in all kinds of tough applications. The entire HD-PRO family (120V/30A to 600V/80A) is designed to trip within 25 milliseconds after ground fault detection at an adjustable selected trip level of 6, 10 or 30 mA.

Before the development of the HD-PRO Series, facilities with high current – high voltage equipment or three phase systems employed expensive ground fault breakers at the source of the branch circuit, or went without ground fault protection, leaving personnel and equipment unprotected.

Circuit breakers can withstand high current levels but have short mechanical lives and were not designed for switching duty. Localized ground faults, with circuit breakers, either shut down the whole branch circuit or were overloaded because the available devices were not portable and were often too costly.

The HD-PRO Series utilizes contactors that are fully rated for motor switching demands. In addition to being far less expensive than three phase breakers, the HD-PRO models protect expensive high current – high voltage equipment at the point of use while offering substantial shock protection for personnel.

TRC is an internationally recognized leader in electrical safety products

that protect equipment, prevent electrical fires and protect against electrocution and serious injury from electrical shock.

Fire Shield Cords and strips prevent fires

Fire Shield products are ideal for home, office, and campus environments such as residence halls, labs, classrooms, libraries and other facilities. Fire Shield cords, with specially designed shielded conductors, are able to detect series faults and line-to-neutral faults, significantly reducing fire hazards. Available as power strips, surge protectors, appliance cords and extension cords. Many universities are requiring Fire Shield products be the only strips used on campus. Based on estimates by the US Consumer Product Safety Commission (CPSC), there are 155,900 electrical fires attended annually by the fire service in the US, resulting in nearly: $1.68 billion in property damage 6,810 injuries 800 deaths Each year across America, college and university students, faculty and staff experience a growing number of fire related emergencies. Annually, there are approximately 1,600 documented fires in college dormitories and Greek housing. In fact, according to the National Association of State FireMarshals (NASFM), fire fighters respond to fires in college dormitories four times a day and numerous fires go unreported. This number does not include the significant amount of fires in other areas such as classrooms, labs and off-campus housing. CPSC statistics indicate that 50%of all electrical fires, attended and unattended by the fire service, were caused by faulty flexible power cords-extension cords, surge strips, and appliance cords. Flexible cords fail in a variety of ways, including: Pinched, Crimped or Frayed Cords Overheated/Overloaded Cords Application-related Damage (i.e. Room air conditioners, heaters, tools, vacuums, etc.) Frequent Movement of Appliance Normal Aging and Wear Extension Cords and Surge Strips are the Solution TRC, the leader in ground fault sensing technology, developed Fire Shield’s unique patented design to provide built-in fire protection in a power cord set. This technology is available as an extension cord and a variety of surge strips. It is also being utilized by many portable room air conditioner manufacturers. The Fire Shield Surge Strips are the only surge strips in the world that can protect against all of the following: Cord Fires Surges Overloads Standard ground fault, surge and overload devices alone cannot prevent cord fires. The patented, UL approved Fire Shield is the only cord set in the world that provides cord fire protection. Fire Shield monitors the leakage current, thus sensing any damage to the cord and shuts off the power safely in 25/1000ths of a second. Using Fire Shield: Protects electrical equipment from damaging power surges and spikes. Shuts off the electricity before a fire can start if it detects damage to its power cord.
