The 100 kA breaking capacity at 400 V AC (and at 500 V and 690 V AC) gives it enough interrupting rating to serve as the sole short-circuit protective device in most industrial panels, eliminating the need for a separate upstream fuse or breaker in many coordination studies. It also detects phase failure, which is critical for preventing single-phasing damage on three-phase motor loads. The 45 mm width and 97 mm depth mean it occupies a single modular slot on the DIN rail, matching the footprint of the SIRIUS 3RV2 family. Any mounting position is permitted, so it fits in horizontal or vertical panel layouts. Clearance requirements: 50 mm upwards and downwards, 30 mm at the sides, 0 mm forwards and backwards — tight enough for dense panel packing but leave the vertical gaps for heat dissipation from the bimetal trip. Breaking capacity: 100 kA at 240 V AC, 400 V AC, 500 V AC, and 690 V AC. This SCCR covers virtually all industrial low-voltage distribution systems up to 690 V. The rated insulation voltage spans 20 to 690 V. For motor sizing reference: at 230 V it handles 0.2 kW, at 460/480 V it handles 1 hp, and at 575/600 V it handles 0.5 hp. The gL/gG fuse backup ratings at 500 V and 690 V are both 16 A. Operating temperature range is -20 to +60 °C with temperature compensation active over the same span; storage and transport range is -50 to +80 °C.","metaTitle":"Siemens 3RV2011-0KA40 SIRIUS Motor Protection CB, 100 kA","metaDescription":"Siemens 3RV2011-0KA40 SIRIUS motor protection circuit breaker, Trip Class 10, 100 kA breaking capacity at 400 V, 45 mm wide.
