It carries a Trip Class 10, meaning it trips within 10 seconds at 7.2× the thermal setting — fast enough to protect standard induction motors during locked-rotor conditions. The breaker is rated for a breaking capacity of 100 kA at 400 V, which covers most industrial panel fault levels without needing an upstream current-limiting fuse. It mounts on a 35 mm DIN rail per DIN EN 60715 and accepts screw-type terminals for the main circuit. ## What the key ratings mean for your BOM line The 100 kA breaking capacity at 400 V means this breaker can safely interrupt a short-circuit fault up to that level without needing an upstream fuse for most installations — a key spec for panel SCCR compliance. The Trip Class 10 is the standard for general-purpose motor starting; it allows the inrush current to pass during start-up but clears quickly on a sustained overload. Phase failure detection is built in, so the breaker will trip if one phase drops out, preventing single-phasing damage to the motor. The 45 mm width and 75 mm depth fit the standard SIRIUS compact footprint, leaving room for auxiliary contact blocks alongside. ## Panel integration and wiring The breaker snaps onto a 35 mm DIN rail (DIN EN 60715) in any mounting position. The main circuit uses screw-type terminals accepting 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²). Clearance: 20 mm upwards and downwards, 9 mm at the side, 0 mm forwards and backwards. No separate fuse is required at 240 V; at 400 V a gL/gG 35 A backup fuse is specified.","metaTitle":"Siemens 3RV1011-1CA10-ZW95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1011-1CA10-ZW95 SIRIUS motor protection circuit breaker, Trip Class 10, 100 kA breaking capacity at 400 V, screw terminals, DIN rail mount.
