Breaking capacity is 100 kA at 240 V, 30 kA at 400 V, 6 kA at 500 V, and 3 kA at 690 V — the 400 V figure is the one that governs most European 400 V line-side installations, and it provides ample SCCR headroom for typical panel coordination. This part carries a lifecycle status of current production, so it remains available through the standard Siemens SIRIUS channel. ## Key Protection Features Ground fault detection is not included, so if that is required, an external ground-fault module or a different SIRIUS variant would be needed. Rated operational voltage spans 20 to 690 V, covering low-voltage motor circuits from 24 V control transformers up to 690 V industrial mains. Dimensions are 55 mm wide, 140 mm high, 149 mm deep — a standard SIRIUS 3RV2 footprint that fits alongside contactors and overloads on the same DIN rail. Main circuit terminals accept screw-type connections: 2× (1 to 25 mm²) or 1× (1 to 35 mm²) solid or stranded, with M6 terminal screws. Maximum switching frequency in AC-3 duty is 15 operations per hour, which suits motor starting cycles for pumps, fans, and compressors — not high-speed jogging or reversing applications.","metaTitle":"Siemens 3RV2031-4BA10-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV2031-4BA10-ZX95 motor protection circuit breaker, CLASS 10 trip, 100 kA at 240 V, 30 kA at 400 V.
