The phase failure detection trips the breaker when one phase drops out, preventing single-phasing motor burnout. Ground fault detection is not built in, so downstream GFCI or RCD is required for personnel protection. The breaker accepts spring-loaded terminals for the main current circuit, accepting 2× 0.5 to 2.5 mm² solid or stranded conductors. Temperature compensation is active across the -20 to +60 °C operating range, so the trip curve stays accurate in a warm enclosure. ## Coordination and Clearances Minimum clearances for safe operation: 50 mm upwards and downwards, 30 mm at the side, 0 mm forwards and backwards — the breaker can be mounted flush against a backplane. The 97 mm depth and 45 mm width fit standard DIN-rail footprints.","metaTitle":"Siemens 3RV2011-1CA25-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV2011-1CA25-ZX95 SIRIUS motor protection circuit breaker. 25 A at 400 V gL/gG, Trip Class 10, 100 kA SCCR.
