Breaking capacity is 100 kA at 240 V, 400 V, 500 V, and 690 V AC — a single rating that covers common industrial supply voltages and gives plenty of headroom for high-fault panels. Front face is IP20; the terminals accept solid conductors from 0.5 mm² up to 2.5 mm² (two per clamp) and stranded up to 6 mm². Shock rated at 25 g for 11 ms. Power dissipation at rated current is 7.25 W in hot operating state.","metaTitle":"Siemens 3RV1021-0KA15-ZW96 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-0KA15-ZW96 SIRIUS motor protection circuit breaker, 1.25 A continuous, CLASS 10 trip, 100 kA breaking capacity at 400 V AC.
