SIRIUS 3RV1011-0EA20-ZX95 — motor protection breaker, 0.4 A, CLASS 10
The Siemens SIRIUS 3RV1011-0EA20-ZX95 is a motor protection circuit breaker designed for a 0.4 A continuous rated current, sized for a 0.09 kW motor at 400 V. Breaking capacity hits 100 kA at 400 V (and at 240 V, 500 V, and 690 V), so it can interrupt a bolted fault up to that level without upstream fuses needing to clear first. That 100 kA SCCR rating covers most industrial panel bus bracing requirements. No ground fault detection on this variant. Spring-loaded terminals on both main and auxiliary circuits accept 2x (0.25 to 2.5 mm²) solid or 2x (0.25 to 1.5 mm²) finely stranded with ferrules. AWG equivalent is 2x (24 to 14). No lug torque to worry about — strip 8 mm, push in, done.
Zero clearance needed at the back or sides, so you can pack it tight on the rail. Rated for any mounting position. Shock rated at 25g / 11 ms — survives the vibration and bump common in panel-mounted gear near conveyors or compressors.
RoHS compliance date is 01.01.2013 — meets the EU RoHS directive. Surge voltage resistance rated at 6000 V, which aligns with IEC 60947-2 overvoltage category III requirements for industrial control panels.
This is a fast-moving critical spare for any panel with 0.4 A motor branches — keep one on the shelf if you've got a line using this amp rating.
