Solid State Contactors ~ 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.
