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. It trips CLASS 10, meaning it clears an overload within 10 seconds at 7.2× the set current — fast enough to protect standard induction motors from locked-rotor heat buildup without nuisance tripping on normal starts. 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. Phase failure detection is built in — if one phase drops, the breaker trips, preventing single-phasing damage on a motor. 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.
Panel fit and mounting
Mounts on 35 mm DIN rail per EN 50022 with either screws or the integrated snap-on foot. Dimensions are 45 mm wide, 90 mm tall, 81 mm deep — fits a standard 45 mm modular device slot. Zero clearance needed at the back or sides, so you can pack it tight on the rail. IP20 on the front means finger-safe touch protection; the terminals are protected against accidental contact. Rated for any mounting position. Operating temperature range is -20 to +60 °C. Shock rated at 25g / 11 ms — survives the vibration and bump common in panel-mounted gear near conveyors or compressors.
Lifecycle and compliance
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.
Sourcing and availability
The 3RV1011-0EA20-ZX95 is sourced and quoted to order through independent distribution. Availability and current pricing are confirmed at quote time against an RFQ. 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.
