The headline figure is 100 kA breaking capacity at 240 V, 400 V, and 500 V — that is the fault current this device can safely interrupt without upstream damage. For selectivity with upstream fuses, the spec calls for gL/gG fuses: 50 A at 400 V, 40 A at 500 V, 35 A at 690 V. That fuse coordination is what keeps a downstream fault from taking out the whole feeder. ## Termination and ratings The main current circuit uses spring-loaded terminals, accepting 2x (0.5 to 4 mm²) solid or stranded wire. No ground-fault or phase-failure detection built in — this is a straightforward motor-circuit protector, not a multifunction monitor. The rated voltage span is 20 to 690 V, covering most low-voltage industrial supplies. Operating temperature range is -20 to +60 °C; storage and transport range is -50 to +80 °C.","metaTitle":"Siemens 3RV2311-1GC20 SIRIUS Circuit Breaker, 100 kA SCCR","metaDescription":"Siemens 3RV2311-1GC20 SIRIUS circuit breaker for starter combinations. 100 kA breaking capacity at 400 V. 45 mm wide, DIN rail mount.
