It drops the breaker when coil voltage falls below the dropout threshold, protecting motors from restarting after a supply dip. Fits the S00, S0, S2, and S3 frame sizes of the 3RV2 breaker range. The front is IP20 finger-safe per IEC 60529, so it's safe to touch in a live panel. Comes with 2 normally-open leading auxiliary contacts (spring-type terminals) that change state before the main contacts — useful for signaling a pending trip to a PLC or safety relay. Pollution degree 3 rated, insulation voltage 690 V.","metaTitle":"Siemens 3RV2922-2CV1 undervoltage release, 415 V AC 50 Hz /","metaDescription":"Siemens SIRIUS 3RV2922-2CV1 undervoltage release for 3RV2 motor circuit breakers. 415 V AC 50 Hz / 480 V AC 60 Hz coil, 2 NO leading aux contacts, spring terminals.
