The 100 kA rating at 400 V AC is consistent across 240 V, 500 V, and 690 V as well — the breaker holds that full interrupting capacity across the common industrial voltage range. That is unusual for a size S00 frame; many compact breakers derate above 480 V. Compared to the 3RV2011-0AA10 (a standard motor protection breaker without the starter-combination designation), the 3RV2311-0EC10 is built for Type 1 or Type 2 coordination with a matching SIRIUS contactor. The 3RV2011-0AA10 is a general-purpose motor protective breaker; the 3RV2311-0EC10 is the version that has been tested and listed for direct mounting to a contactor in a starter combination, saving panel space and wiring. ## Panel Integration and Clearances Required clearances: 50 mm above and below the breaker for air circulation and arc-quenching, 30 mm to the side, and zero clearance forwards or backwards — meaning it can be mounted flush against a backplate or enclosure wall without derating. Screw terminals on the main circuit accept 2x 0.75 to 2.5 mm² solid or stranded, or 2x 4 mm². The screwdriver shaft diameter is 5 to 6 mm, Pozidriv size 2 — a standard electrician's screwdriver fits without a special bit.","metaTitle":"Siemens 3RV2311-0EC10 SIRIUS Circuit Breaker, 100 kA at 400","metaDescription":"Siemens 3RV2311-0EC10 SIRIUS circuit breaker for starter combinations. 100 kA breaking capacity at 400 V AC. 45 mm wide, screw and snap-on DIN rail mount.
