The breaker is rated for a 0.25 kW motor at 400 V and offers a 100 kA breaking capacity at 400 V AC, which safely interrupts fault currents up to that level without upstream fuses needing to clear first. Screw-type terminals on both main and auxiliary/control circuits accept solid or stranded conductors: 2× (1 … 2.5 mm²) and 2× (2.5 … 6 mm²), or AWG 14–10 for main contacts. An auxiliary switch can be added. Mounting position is any.","metaTitle":"Siemens 3RV1021-0JA10-ZW96 SIRIUS Motor Protection CB, 1 A,","metaDescription":"Siemens 3RV1021-0JA10-ZW96 SIRIUS motor protection circuit breaker, 1 A continuous, CLASS 10 trip, 100 kA breaking capacity at 400 V.
