645T Series - Solid State On / Off Motor Relays
Motor Relays
The 645T series of solid state relays uses triacs for on/off 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 50 amps and up to a nominal voltage of 480VAC. Both random turn on or zero cross is available.
