Motor Protection Circuit Breaker for the Panel Builder
The Siemens SIRIUS 3RV1011-1GA10-0FJ0-ZX95 is a motor protection circuit breaker designed for the 6.3 A continuous current range, sized for a 2.2 kW motor at 400 V.
The 100 kA breaking capacity at 400 V AC is the headline number, but note the derating at higher voltages: 3 kA at 500 V and 2 kA at 690 V. The 6 kV rated surge voltage resistance confirms it handles switching transients on a 400 V system without flashover.
Integration and Wiring
Screw-type terminals accept 2x (0.5...1.5 mm²) solid or 2x (0.75...2.5 mm²) stranded conductors, AWG 2x (18...14). 45 mm width, 90 mm height. Any mounting position; -20 to +60 °C operating range.
