Two Contactors Reverser

Reverser Application Description

A reverser contactor pair allows the control of a three–phase motor in two directions.

It switches the order of the phases supplying the motor from UVW to UWV:

  • Phase rotation is UVW: the motor rotates forward.

  • Phase rotation is UWV: the motor rotates reverse.

The two contactors must be mechanically and electrically interlocked to prevent that both contactors are closed in the same time.
