CARLO GAVAZZI's newest addition to its RGC Series Solid State Contactor platform - single-phase zero-crossing relays, features an integral heat sink. They offer the best in the class current rating of up to 37 AAC at 40°C or 43 AAC at 25°C.

With the introduction of the RGC..32, Carlo Gavazzi now offers a solution for switching up to 37 AAC at 40°C that fits in the 17.8mm wide platform with a depth of 103mm. The RGC..32 is offered both with screw as well as box clamp output terminals. The version with box clamps is rated 37 AAC @ Ta 40°C. This higher current rating on the 17.8mm compact platform is achieved through the utilization of a higher rated power chip that has an I²t of 18000 A²s.  Due to this high I²t specification, the RGC..32 can be protected against short circuits by B curve Miniature Circuit Breakers, in applications where the UL508 SCCR rating is not required.

The main benefits of the RGC..32 include the fact it has the highest amperage rating of any 17.8 or 22.5mm wide solid state switching devices available on the market, DIN rail spacing over 22.5 mm platform, optional cage clamp power terminal for wires up to 3 AWG size, and energy savings due to lower power dissipation.

The specifications of the RGC..32 Series include:


  • AC Amperage ratings of up to:
    • 37A AC at 40°C
    • 42A AC at 25°C     
  • Compact 17.8mm width housing
