The Siemens SIRIUS 3RV2311-0FC10 is a circuit breaker designed specifically for starter combinations, size S00. It mounts via screw and snap-on onto 35 mm standard mounting rail per DIN EN 60715, in any mounting position. At 45 mm wide and 97 mm deep, it fits compactly into a motor control center or panel.
Panel integration is straightforward. The 45 mm width and 97 mm depth fit standard DIN-rail spacing; the 97 mm height leaves room for busbars or wiring ducts above and below. Clearance requirements: 50 mm upwards and downwards, 30 mm to the side — no clearance needed forwards or backwards. The screw-type terminals for the main circuit accept 2x (0.75 to 2.5 mm²) solid or stranded, or 2x 4 mm². Screwdriver shaft diameter 5 to 6 mm, Pozidriv size 2 tip.
Rated for 100 kA breaking capacity at 400 V AC — that's the SCCR you need for high-fault industrial panels. The operating temperature range is -20 to +60 °C, storage and transport -50 to +80 °C. No ground fault or phase failure detection built in; this is a straightforward thermal-magnetic breaker for motor branch circuits.
