| Series Features |
| 645RT Series - Solid State Reversing Motor Relays |
| Series Description: The 645RT series of solid state relays uses triacs for reversing phases on three phase loads. The most typical use is motor reversing. Inputs are DC operated. Load currents can range from 10 to 40 amps and up to a nominal voltage of 480VAC. Both random turn on or zero cross is available. |
