Motor horsepower ratings are listed per voltage: 2 hp at 200/208 V, 5 hp at 460/480 V and 575/600 V, and 1 hp at 230 V — these are the NEMA-equivalent loads the breaker can handle in AC-3 duty. Dimensions: 45 mm wide, 106 mm high, 97 mm deep — the width is a single modular unit, so it occupies one slot on the DIN rail. Lifecycle stage is current production.","metaTitle":"Siemens 3RV2311-1HC20 SIRIUS Circuit Breaker, 100 kA at 400","metaDescription":"Siemens 3RV2311-1HC20 SIRIUS circuit breaker for starter combinations. 100 kA breaking capacity at 400 V AC.
