This is the standard choice for most conveyor, pump, and fan applications. Ground fault detection is not included — that would require an external core-balance relay or a separate ground-fault module. The interrupting ratings are given at multiple voltages, which matters for panel coordination. At 240 V it can clear 100 kA; at 400 V it handles 30 kA; at 500 V it drops to 4 kA; at 690 V it manages 2 kA. The 30 kA at 400 V is the figure most European panel builders will check first — it determines whether this breaker can be used without a current-limiting upstream fuse in a typical 400 V industrial supply with a 25 kA prospective fault level. Motor power ratings: 18.5 kW at 230 V, 25 hp at 220/230 V, 50 hp at 460/480 V. These are the AC-3 (squirrel-cage motor starting) ratings that govern the motor FLA it can protect. The 55 mm width and 149 mm depth are the dimensions that matter for panel layout — it occupies a single 55 mm module on the rail. The side clearance of 10 mm is tight — adjacent devices can be butted close, but the 50 mm vertical clearance above and below is needed for arc-quenching and heat dissipation. Main circuit terminals accept 2× (1–35 mm²) or 1× (1–50 mm²) solid or stranded copper. Screw-type terminals with M6 thread.","metaTitle":"Siemens 3RV2031-4JA10-ZW97 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV2031-4JA10-ZW97 motor protection circuit breaker, CLASS 10 trip, 100 kA at 240 V, 30 kA at 400 V.
