It trips in Class 10, meaning it clears an overload within 10 seconds at 7.2× the thermal setting — fast enough to protect standard induction motors during a locked-rotor event. The breaker carries a 100 kA breaking capacity at 400 V AC, so it can safely interrupt fault currents up to that level without upstream fuses needing to clear first. ## Mounting and wiring Mounts on 35 mm DIN rail per DIN EN 60715 using either the screw or snap-on method. The 45 mm width fits standard panel spacing. Spring-loaded terminals on the main circuit accept 2× (0.5 to 4 mm²) solid or stranded wire — no screw torque to verify, just strip and push. Any mounting position works, but leave 50 mm clearance above and below, 30 mm to the sides, and zero forward clearance needed.","metaTitle":"Siemens 3RV2011-1AA20-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV2011-1AA20-ZX95 motor protection circuit breaker, Class 10, 100 kA breaking capacity at 400 V, spring-loaded terminals, DIN rail mount.
