3 phase SSR (triac output 10A to 40A)

GT 10 to 40 Amps AC SSR

The series GT three phase Solid State Relays is used three phase loads. Triac Output. The triac version of the zero switching relay is an inexpensive solution for resistive loads. The zero switching relay switches on when the AC sine voltage just crosses zero, and switches off when the current crosses zero.

- Three phase Solid State Relays
- Rated operational current 3x10, 3x15, 3x25 and 3x40 Amps.
- Rated operational voltage 440 V.
- Zero switching for resistive loads.
- Input Voltage Range 4 to 16 Vdc, 3 to 32 Vdc.
- 2500 Vrms Optical Isolation.(input/output)
- LED-indication for control input.
