It operates on a 400V AC, 50Hz control supply. The 400V AC 50Hz rating defines the nominal coil voltage and frequency. This release mounts directly onto the side of the 3RV breaker — no separate wiring compartment needed. The dropout characteristic ensures the breaker opens when the control supply falls below roughly 70% of rated voltage, which is the standard undervoltage protection threshold for motor circuits per IEC 60947-2.","metaTitle":"Siemens 3RV1902-1AV00-0FJ0 Undervoltage Release, 400V AC 50H","metaDescription":"Siemens 3RV1902-1AV00-0FJ0 undervoltage release, 400V AC 50Hz, for SIRIUS 3RV circuit breakers size S00 to S3.
