Designed specifically for starter combinations, it integrates into motor control centers where coordination with contactors and overloads is critical. Rated voltage spans 20 to 690 V AC, and the AC-3 operational current at 400 V matches the continuous rating at 400 A, so it switches motor loads up to that current under full load. The electronic short-circuit trip provides precise, adjustable protection curves. Mounting position is any orientation, with screw fixing to the panel backplate. ## Sizing and deployment context Shock rated at 12g for 11 ms, so it holds up in mobile or high-vibration installations. Maximum installation altitude is 2 000 m above sea level.","metaTitle":"Siemens 3RV1374-7GN10 SIRIUS MCCB, 400 A, 200 kA at 400 V","metaDescription":"Siemens SIRIUS 3RV1374-7GN10 molded-case circuit breaker, 400 A continuous, 200 kA breaking capacity at 400 V AC.
