It is designed for screw-type terminal connections on both the main and auxiliary/control circuits. ## Breaking capacity and fault clearing Rated breaking capacity reaches 100 kA at 240 V AC, 50 kA at 400 V AC, 10 kA at 500 V AC, and 4 kA at 690 V AC. Ground fault detection is not integrated, meaning a separate residual-current device is needed if ground-fault protection is required. Any mounting position is permitted, which simplifies panel layout. Zero clearance required at the sides and rear (0 mm), so units can be ganged without spacing gaps — useful when packing multiple breakers into a tight enclosure. Power dissipation in hot operating state is 10.5 W. In a sealed, non-ventilated enclosure, account for this heat contribution when sizing the thermal management. Shock resistance rated at 25 g for 11 ms. Main circuit screw terminals accept solid conductors: 2× (0.5 to 1.5 mm²) and 2× (0.75 to 2.5 mm²). Stranded conductors: 2× (1 to 2.5 mm²) and 2× (2.5 to 6 mm²). AWG equivalents for main contacts: 2× (14 to 10). The auxiliary switch uses transverse screw terminals. This is a current-production Siemens SIRIUS device.","metaTitle":"Siemens SIRIUS 3RV1021-4CA15-ZW97 Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-4CA15-ZW97 motor protection circuit breaker.
