It switches 11 kW at 400 V in AC-3 duty (motor starting/stopping), and the interrupting ratings hit 100 kA at 240 V AC and 50 kA at 400 V AC, so it handles high-fault-current panel feeds without cascading upstream. ## Coordination & Selectivity No ground fault detection, so that function must come from a separate module or upstream device if required. The 14.5 W power dissipation in hot operating state matters for panel thermal budgeting when grouping multiple breakers in an enclosure — derating curves apply above 40 °C ambient. Zero clearance at the sides and rear — no air gap needed between adjacent units, so it packs tight on the rail. Screw-type box terminals for the main circuit accept stranded up to 25 mm² (2x) or 35 mm² (1x); auxiliary and control circuits also use screw terminals. Solid wire range for aux circuits is 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²). Dimensions: 55 mm wide, 140 mm high, 149 mm deep. Mounting position any orientation.","metaTitle":"Siemens SIRIUS 3RV1031-4DB15-ZX95 Motor Protection CB, 25 A,","metaDescription":"Siemens SIRIUS 3RV1031-4DB15-ZX95 motor protection circuit breaker. 25 A continuous, CLASS 20 trip, 11 kW at 400 V.
