Carlo Gavazzi Earth Leakage Monitors

Carlo Gavazzi Earth Leakage (grounding) Monitor Relays

CARLO GAVAZZI is proud to announce the launch of two new Earth Leakage Monitoring Relays, the DEA71 and DEB71. When used in conjunction with a CTG Series Core Balance Current Transformer and appropriate circuit breaker, they provide machine protection against fault currents, and help to reduce fire hazards. These earth leakage relays react to small changes in current which can occur due to insulation or grounding failure.

Two models, each offering choices of threshold ranges, allow users to find the right solution for their unique requirements. The DEA71 features fixed trip levels which offer time-saving installation, with a reliable tripping level and safety against tampering. The DEB71 provides ability to adjust trip levels and includes an adjustable time delay; a lockable front cover provides further tamper protection.
A key advantage offered by DEA71 and DEB71 is avoidance of nuisance tripping in the circuit, in accordance with the EN 60947-2 Annex M norm. Two separate alarm outputs allow for a warning signal to be generated before a shutdown is necessary. Their compact (35mm wide) housing preserves valuable panel space.
The DEA71 and DEB71 from Carlo Gavazzi perform crucial monitoring of earth leakage, prolonging machine life by limiting damage from ground faults as well as reducing fire risk. They conform to global standards such as UL 508, CSA C22.2 and EN 60947-2 Annex M.
The features of the DEA71 and DEB71 Earth Leakage Relays include:

 

•   DEA71 includes two models with fixed trip setting: 30 mA and 300 mA
  
•   DEB71 includes two models with adjustable trip levels: 30 mA to 5 A and 300 mA to 30 A
  

 2 SPDT relay outputs, for warning and for alarm  24 VAC to 240 VAC power supply
 NORM DIN-rail housing 35 mm
 Lockable lid on adjustable models (DEB71)

The DEA71 and DEB71 Monitors and CTG Series Core Balance Current Transformers are available from

IMS Electric Meters, Integrated Metering Systems

Integrated Metering Systems, Inexpensive Electric Meters

IMS - Integrated Metering Systems

Since 1989 IMS has been manufacturing current transformer (CT) rated electric submeters. These products quantify electrical energy for dozens of applications, including tenant billing, energy management, solar PV production, cost accounting, or any other application where an accurate, easy-to-install electric meter is required.

Unlike most electric utility meters, our revenue grade CT-rated meters do not plug into a meter socket, so there is no need to re-route power wires. No other electronic meter manufacturer has the confidence and experience to offer a ten-year warranty, and our unique and diverse array of product offerings cover almost any residential, commercial, or industrial application. Our commitment is to 100% customer satisfaction!

Mini Meters

Designed for residential applications, these 100A, 200A, and 400A electric submeters are perfect for metering electric consumption or production for nearly any 120V 2-wire or 120/240V 3-wire application. These revenue-grade single phase (120V 2-wire or 120/240V 3-wire) kWh meters make tenant submetering a snap! Available in indoor flush-mount, outdoor surface-mount, or NEMA 4X Multiple Meter Units (MMUs). Also available in UL Listed, NEMA 4X Multiple Meter Units (MMUs), with up to nineteen meters per enclosure.

Current Transformers

Split Core vs. Solid

Should I order split core or solid core CT's? What's the difference?

Solid Core

Solid core Current Transformers (CTs) look like donuts with wires attached. These ring-shaped devices slip over the power lines and measure the electrical current flowing through the line. The CT "secondary" wires connect to the meter, facilitating power and energy calculations.

Solid core CTs are very accurate (0.3% maximum error), small in size, and inexpensive. However, power must be turned off and the circuit opened, generally at a circuit breaker, so that the solid core CT can be slipped over the power line. After installation the power wire must be reconnected to close the electrical circuit. Installation usually only takes a minute or two per CT.

Split Core

Split core CTs can be taken apart, or ‘split' into halves, which negates the need to turn power off and open the circuit during installation. This saves a little installation time, and for critical loads that cannot be switched off, split core CTs are a must. However, split core CTs are more expensive, bulkier, and not as accurate as solid core CTs.
