The Siemens SIRIUS 3RV1041-4MA10-ZX95 is a motor protection circuit breaker rated for 100 A continuous current with a 45 kW motor rating at 400 V AC, Class 10 trip curve. The Class 10 trip means it clears overloads within 10 seconds at 7.2× the thermal setting — fast enough to protect standard induction motors during a stall or jam without nuisance tripping on normal starting inrush.
The 70 mm width and 174 mm depth fit standard panel layouts; zero clearance needed at the back or sides for heat dissipation (0 mm backwards, 0 mm at the side). Main circuit terminals accept solid conductors 2× (2.5…16 mm²) or stranded 2× (10…50 mm²), single up to 70 mm². Auxiliary and control circuit terminals are screw-type, separate from the main power path.
