The 645S series of solid state relays uses back to back SCRs for on/control of three phase loads.

Operation is three pole normally open. Inputs can be AC or DC operated. Load currents can range

from 10 to 75 amps and up to a nominal voltage of 480VAC. Both random turn on or zero cross

construction is available.
