APPLICATION WITH ONE PHASE MOTOR
The EMCRT relay, initially developed to reverse threephase asynchronous motors, can be used for reversing single phase motors. This relay has four power
switches, a reversing temporization and a lock in case
of simultaneous controls. If you need large quantities for
single-phase use, please contact us. We can simplify the
product because only two switches of four are used.
