What the 100 kA SCCR and Class 10 trip mean for your panel
The Siemens 3RV1011-0FA15 is a SIRIUS motor-protective circuit breaker rated for 100 kA short-circuit breaking capacity at 400 V, 500 V, and 690 V — meaning it can safely interrupt a fault up to that level without cascading damage upstream. That SCCR figure governs the panel label; if your available fault current sits below 100 kA, this breaker covers it without needing a current-limiting fuse ahead. The Class 10 trip characteristic means the bimetal releases within 10 seconds at 7.2× the thermal setting, which lines up with standard IEC motor starting profiles — a pump or conveyor starting under load won't nuisance-trip, but a locked rotor clears fast enough to protect the winding. At 230 V it's sized for a 0.1 kW motor load; the auxiliary contact block handles 1 A at 24 V and 2 A at 120 V, so it can drive a PLC input or a contactor coil directly without an interposing relay.
Mounting and integration — screw and snap-on DIN rail
Mounts via screw and snap-on onto 35 mm standard mounting rail per DIN EN 60715. Any mounting position is allowed, so you can orient it vertically or horizontally in the panel to fit tight gland-plate layouts. Dimensions: 45 mm wide, 90 mm tall, 75 mm deep — a standard 45 mm module width that matches the SIRIUS contactor footprint for a direct line-side feed. Spacing requirements: 20 mm upward, 20 mm downward, 9 mm at the side.
Environmental range and wiring
Rated for operation from -20 to +60 °C, storage and transport from -50 to +80 °C. Terminal capacity: 2× (0.5 to 1.5 mm²) solid or stranded, or 2× (0.75 to 2.5 mm²). Main contact screws are M3.
