Depth is 97 mm, which matches the contactor depth in the same frame class; no extra gland-plate projection. ## Motor ratings and coordination Rated for motor loads: 2 hp at 230 V, 5 hp at 220/230 V, 10 hp at 460/480 V. The AC-3e switching capacity is 15 operations per hour maximum — fine for a pump or fan cycling a few times an hour, not for a jogging or reversing application. Screw terminals accept 2x 0.75–2.5 mm² or 2x 4 mm² solid/stranded. No ground-fault or phase-failure detection built in; that's handled by the upstream motor protection relay or the contactor's electronic overload.","metaTitle":"Siemens 3RV2311-4AC10 SIRIUS Circuit Breaker, 100 kA at 240","metaDescription":"Siemens 3RV2311-4AC10 SIRIUS circuit breaker for starter combinations. 100 kA breaking capacity at 240 V, screw terminals, DIN rail mount.
