Dimensions are 176 mm deep, 70 mm wide, and 165 mm high, fitting standard 70 mm-wide DIN-rail slots. Clearance requirements: 150 mm above and below for air circulation and arc quenching, 30 mm to the sides, and zero clearance forward or backward — so it can be butted against a backplane or enclosure wall without derating.","metaTitle":"Siemens 3RV2342-4MC10 SIRIUS Circuit Breaker, 100 kA at 400","metaDescription":"Siemens 3RV2342-4MC10 SIRIUS circuit breaker for starter combinations.
