It's built for the panel — screw and snap-on onto 35 mm DIN rail per EN 50022, and the spring-loaded terminals on the main circuit accept 2x (0.25…2.5 mm²) solid or 2x (0.25…1.5 mm²) finely stranded with ferrules. Class 10 trip protects standard induction motors during stall or overload, and the phase failure detection catches a lost phase before the winding cooks. At 240 V it jumps to 100 kA; at 500 V it drops to 3 kA, and at 690 V to 2 kA. The 6 000 V surge voltage resistance (rated impulse withstand) gives selectivity headroom for the downstream contactor. Mounting position any — fine for horizontal or vertical DIN-rail layouts. IP20 on the front; the 45 mm width and 81 mm depth fit standard enclosure gland plates. Shock rated at 25g / 11 ms — shrugs off the vibration you get near crushers and conveyors. ## Power dissipation Dissipates 9.25 W total in hot operating state at rated current, 3.1 W per pole.","metaTitle":"Siemens 3RV1011-1KA20-ZW98 SIRIUS Motor Circuit Breaker, 12","metaDescription":"Siemens SIRIUS 3RV1011-1KA20-ZW98 motor-protective circuit breaker, 12 A continuous, 5.5 kW at 400 V, Class 10 trip, 50 kA breaking at 400 V.
