This is a standard feature on SIRIUS motor-protection breakers and saves adding a separate phase-monitor relay. At 45 mm wide, it occupies a single modular unit — useful when packing multiple motor branches into a compact panel. Main circuit terminals are screw-type, accepting 2x (1 … 2.5 mm²) solid or stranded, or 2x (2.5 … 6 mm²) — covers common motor-feeder wire sizes up to 6 mm². No auxiliary contacts are pre-installed (0 supplied), but the breaker accepts add-on auxiliary switch blocks if remote status signaling is needed.","metaTitle":"Siemens 3RV1021-1JA10-ZW96 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-1JA10-ZW96 motor protection circuit breaker, 10 A continuous, CLASS 10 trip, 100 kA breaking at 400 V AC.
