The Siemens 3RV1902-1AV10-0FJ0 is an undervoltage release for the SIRIUS 3RV series of circuit breakers, rated 480V AC at 60Hz. It fits breaker sizes S00 through S3, meaning it covers the full range of standard motor-protective and circuit-breaker frames in that family. When line voltage drops below the dropout threshold, the release trips the breaker — a standard undervoltage protection function for preventing automatic restart after a power loss.
