The 100 kA rated short-circuit breaking capacity at 400 V AC means this breaker can safely interrupt a fault current up to 100,000 A at that voltage without welding contacts or cascading failure upstream — critical for high-fault-current industrial panels where the available fault current at the panelboard exceeds typical 25 kA or 65 kA ratings. Rated operational voltage spans 20 to 690 V, covering standard low-voltage motor circuits up to 690 V three-phase. The AC-3 maximum switching rate of 15 1/h sets the limit for frequent motor starts — suitable for conveyor or pump cycling but not for high-speed jogging applications. At 230 V, the motor power rating is 0.1 kW — a low figure that reflects this breaker's role in the smallest S00 frame, intended for fractional-horsepower motors or control transformers rather than main drives. The spring-loaded terminals on the main current circuit accept 2x (0.5 to 4 mm²) solid or stranded wire, using a 3 mm screwdriver shaft. Clearance distances: 50 mm upward and downward, 30 mm to the side, 0 mm forward and backward — the forward zero means it sits flush against the mounting surface, so panel depth planning must account for the 97 mm body plus any wiring projection. No ground fault or phase failure detection built in — this is a basic thermal-magnetic or electronic motor-protective breaker without integrated monitoring. If those functions are needed, they must be added externally via a separate relay or a more advanced SIRIUS variant. ## Integration into a panel The any-position mounting simplifies layout in crowded enclosures.","metaTitle":"Siemens 3RV2311-0GC20 SIRIUS Circuit Breaker, 100 kA SCCR","metaDescription":"Siemens SIRIUS 3RV2311-0GC20 circuit breaker for starter combinations.
