The release fits all frame sizes S00, S0, S2, S3. Depth is 68 mm, height 90 mm, width 19 mm. The ring terminal lug connection accepts standard ring lugs; strip length and crimp tool follow the lug manufacturer's spec. Pollution degree 3 (industrial environment with conductive pollution). Maximum break time is 20 ms. The short-circuit protection for the release circuit should be a fuse per the design. The 2 NO leading contacts provide an early open signal before the main breaker trips — useful for sequencing downstream contactors or drives off before the power circuit drops. The release is designed for use with motor circuit breakers (suitability: motor circuit breaker). Reference code per EN 61346-2 is F. Substance prohibitance date per RoHS-like compliance is 05/01/2012.","metaTitle":"Siemens 3RV2922-4CV1 SIRIUS Undervoltage Release, 415/480 V","metaDescription":"Siemens 3RV2922-4CV1 SIRIUS undervoltage release for 3RV2 motor circuit breakers. 415 V AC at 50 Hz, 480 V AC at 60 Hz, 2 NO leading contacts, ring lug terminals.
