Three Phase Solid State Relays (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.
