The Siemens SIRIUS 3RV1011-0EA10-ZI45 is a motor protection circuit breaker in size S00, designed for protecting small induction motors against overload and short circuit. Its CLASS 10 trip characteristic means it will trip within 10 seconds at 7.2× the set current — fast enough to protect a motor winding during a stalled-rotor condition without nuisance tripping on normal starting inrush. The adjustable overload release spans 0.28 to 0.4 A.
Mounting and integration
Mounts via screw or snap-on onto 35 mm standard mounting rail per DIN EN 60715, in any orientation. Size S00 keeps the footprint compact — 45 mm wide — so it fits tightly in a crowded panel. Screw-type terminals on top and bottom accept 2×(0.5…1.5 mm²) solid or 2×(0.75…2.5 mm²) stranded; strip length 8 mm, torque 0.8…1.2 N·m (Pozidriv size 2). No forward clearance required; side clearance 9 mm, top/bottom 20 mm.
