    110 V, 240 V


The RSR-72 type relay for restart and re-acceleration is used in restarting automatic motors, following control and protection device opening, as a result of a brief line voltage interruption or drop-out. This product permits the automatic restart with an accurate sequence which depends on the working process, succeeding the halt of the motors. It is primarily used in relation with a holding posuition contact.

Setting memory time is feasible from 0.4 to 60 seconds and 0.4 to 1,000 seconds of delay time. Everytime a voltage is lacking, it restores the voltage during the memory time set. It restarts the motor after its deactivation due to the delay set. It will not automatically restart if the voltage was restored after the memory time. Its voltage will restore in less than 0.4 seconds and then the motor will re-accelerate.
