Main circuit connections are screw-type terminals accepting 2× (1…2.5 mm²) solid or stranded, or 2× (2.5…6 mm²) — covers most motor feeder cable sizes up to 6 mm². IP20 protection on the front; suitable for enclosed panel use where no washdown or dust ingress is expected. ## Key ratings in context Power dissipation is 7.25 W total in hot operating state (2.4 W per pole), so panel thermal rise is modest — no forced cooling needed in most enclosures.","metaTitle":"Siemens 3RV1021-0JA10-ZW97 SIRIUS Motor Protection CB, 1 A,","metaDescription":"Siemens 3RV1021-0JA10-ZW97 SIRIUS motor-protection circuit breaker, 1 A continuous, CLASS 10, 100 kA breaking capacity at 400 V.
