It trips the breaker when supply voltage drops below the release threshold, protecting downstream loads from undervoltage conditions — a common requirement on motor circuits and conveyor drives where a restart after a sag could cause mechanical damage or unsafe restart. Rated for 400V AC at 50Hz, it mounts directly onto the breaker body, size S00 up through S3.","metaTitle":"Siemens 3RV1902-1AV00-0FQ0 Undervoltage Release, 400V AC","metaDescription":"Siemens 3RV1902-1AV00-0FQ0 undervoltage release for circuit-breakers size S00...S3. 400V AC, 50Hz.
