The overload release is thermal (bimetal), the short-circuit trip is magnetic. ## Breaking capacity and mounting Rated breaking capacity is 100 kA at 240 V, 400 V, and 500 V AC, dropping to 2 kA at 690 V AC. IP20 on the front; no washdown rating, so keep it inside the enclosure.","metaTitle":"Siemens 3RV1011-0KA15-0BA0 SIRIUS Motor Protective Circuit B","metaDescription":"Siemens 3RV1011-0KA15-0BA0 SIRIUS motor-protective circuit breaker, 1.25 A continuous, Class 10, 100 kA breaking at 400 V.
