The Siemens 3RV2411-0DA15 is a SIRIUS-brand circuit breaker specifically designed for transformer protection. Trip class is CLASS 10, and the unit includes phase failure detection.
Breaking capacity and voltage range
Rated for a voltage range of 20 to 690 V, with a symmetrical breaking capacity of 100 kA at 400 V AC and at 690 V AC.
Mounting position is any orientation. Screw-type terminals for the main current circuit accept 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²). Clearance distances: 50 mm upward and downward, 30 mm at the sides, 0 mm forward and backward — important for panel layout when grouping multiple breakers.
Environmental and auxiliary specs
The auxiliary contact ratings: 1 A at 24 V, 0.5 A at 120/125/230 V, 0.15 A at 60 V — these matter for the control circuit interfacing with a PLC or safety relay.
