The 45 mm width and 96 mm depth mean it occupies a single standard module slot on the rail, leaving adjacent space for a contactor or overload relay. Screw-type terminals on the main circuit accept solid conductors 2x (0.5…1.5 mm²) and 2x (0.75…2.5 mm²), or stranded 2x (1…2.5 mm²) and 2x (2.5…6 mm²). No auxiliary contacts are factory-fitted, but the transverse auxiliary switch design allows field-mounting a later block if needed.","metaTitle":"Siemens 3RV1021-0EA15 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1021-0EA15 SIRIUS motor protection circuit breaker, 0.4 A continuous rating, CLASS 10 trip, 100 kA breaking capacity at 400 V.
