| Series Features |
| 645S Series - Solid State On / Off Motor Relays |
| Series Description: 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. |
