Any mounting position is allowed, simplifying layout in tight panels. ## Protection features and wiring Built-in phase failure detection protects motors against single-phasing — a common failure mode in three-phase lines that can burn out windings if undetected. No ground fault detection, so if that's required, add an external GF relay. Main circuit terminals accept screw-type connections, rated for 2× (0.5…1.5 mm²) solid or stranded, or 2× (0.75…2.5 mm²). Torque spec for M3 screws — standard for this class. Maximum switching frequency in AC-3 duty is 15 operations per hour — fine for pump and conveyor cycling, but not for high-repetition applications like stamping presses.","metaTitle":"Siemens 3RV1011-0KA10-ZW95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1011-0KA10-ZW95 motor protection circuit breaker, Class 10, 100 kA breaking capacity at 400 V.
