The RSR-72 type relay for re-start and reacceleration is designed to perfomr the automatic motor restarting, after control and protection device opening, as a consequence of a momentary line voltage interruption or drop-out.
The RSR-72 relays allow, after the stop od the motors, the automatic re-start with a correct sequence depending of the working process.
The RSR-72 relays are housed in a case for flush mounting or panel mounting or on DIN rail 35mm on extractible undecal type. On front panel there are potentiometeres and micro-switches for settings and one LED to indicate the functional status.
