Monitoring relay - Series 3RR. The SIRIUS 3RR21 and 3RR22 current monitoring relays are suitable for load monitoring of motors or other loads. They monitor the RMS value of alternating currents for voltage overloads or undercuts of the set threshold values in 2 or 3 phases. Monitoring relays for mounting on contactor 3RT2 for contactors of size S00 or S0. Adjustable either analog or digital for alarm and warning monitoring for phase faults with excessive or insufficient current, phase sequence errors with broken conductors, as well as warnings and alarms for reverse current. Screw connection/spring terminal, output contact as a 1-pole changeover switch.
