The Trip Class 10 characteristic ensures fast disconnection during overloads, protecting the transformer winding from thermal stress. The 100 kA breaking capacity at 400 V AC (and also at 240 V, 500 V, and 690 V AC) means this breaker can safely interrupt very high fault currents without failing — critical for transformer primary-side protection where inrush and fault currents can be severe. The rated operational voltage spans 20 to 690 V, covering most low-voltage industrial supplies. Ground fault detection is not included, so if that's required, an external GFCI module is needed. Auxiliary contact ratings are provided for control circuit integration: 1 A at 24 V, 0.5 A at 120/125/230 V, and 0.15 A at 60 V. These are the switching capacities for the built-in auxiliary contacts, not the main power path. Any mounting position is permitted. Clearance requirements: 50 mm upwards and downwards, 30 mm at the side, 0 mm forwards and backwards. Screw-type terminals on the main current circuit accept 2x (0.5...1.5 mm²) or 2x (0.75...2.5 mm²) solid or stranded wire. Main contact terminal screws are M3. The design is for transformer protection, so it's sized for the inrush and sustained load profile of a transformer, not a motor. ## Environmental and Operating Conditions The maximum switching frequency at AC-3 and AC-3e duty is 15 operations per hour.","metaTitle":"Siemens 3RV2411-0BA15 SIRIUS Circuit Breaker, Transformer Pr","metaDescription":"Siemens 3RV2411-0BA15 SIRIUS circuit breaker for transformer protection. 100 kA breaking capacity at 400 V AC.
