It is designed for motor protection duty, with phase failure detection built in (no ground fault detection). Rated for 22 kW at 400 V AC-3, this breaker handles the starting and running current of a 22 kW motor on a 400 V three-phase line. The breaking capacity is 50 kA at 400 V AC, 100 kA at 240 V, stepping down to 10 kA at 500 V and 4 kA at 690 V — so it safely interrupts fault currents up to those levels without upstream cascading, provided the available fault current at the panel is within these limits. Dimensions are 55 mm wide × 140 mm high × 149 mm deep, which fits a standard 3-module width on the rail. Main circuit terminals accept screw-type box terminals: solid conductors 2× (0.75…16 mm²), stranded 2× (0.75…25 mm²) or single 1× (0.75…35 mm²). AWG equivalents for the main contacts are 2× (18…2) and 1× (18…2). Auxiliary and control circuits use separate screw terminals. The backwards clearance is 0 mm — the breaker can be mounted flush against a panel wall or adjacent device without rear access needed. Shock resistance is 25 g for 11 ms. The part is RoHS-compliant per the substance prohibition date of July 1, 2006. Power dissipation in hot operating state is 29 W total (9.7 W per pole).","metaTitle":"Siemens 3RV1031-4HA10-ZW97 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1031-4HA10-ZW97 motor protection circuit breaker, 50 A continuous, Class 10 trip, 22 kW at 400 V, 50 kA breaking capacity.
