The 3RV2332-4SC10 delivers 100 kA breaking capacity at 240 V AC and 50 kA at 400 V AC — per the datasheet, these are the short-circuit current levels it can safely interrupt without welding contacts or rupturing the housing. At 500 V AC it still holds 10 kA, and at 690 V AC it manages 5 kA, so it covers the common industrial voltage tiers from 240 V single-phase up to 690 V three-phase. ## Mounting and integration details Dimensions are 55 mm wide, 140 mm high, and 149 mm deep — the 55 mm width means it occupies three standard 18 mm DIN-rail module spaces, so plan your rail fill accordingly. Clearance requirements: 50 mm upwards and downwards, 10 mm to the side, and 0 mm forwards or backwards — the zero forward clearance means it can be mounted flush against a panel door or cover without extra breathing space. Main contacts use M6 screw-type terminals; the wiring range accepts 2x (1 to 35 mm²) or 1x (1 to 50 mm²) solid or stranded copper — sized for the motor feeder currents this breaker typically protects.","metaTitle":"Siemens 3RV2332-4SC10 SIRIUS Circuit Breaker, 50 kA at 400 V","metaDescription":"Siemens 3RV2332-4SC10 SIRIUS circuit breaker for starter combinations. 50 kA breaking capacity at 400 V AC.
