Power dissipation runs 5.5 W total hot, 1.8 W per pole — panel builders need to account for that in a sealed enclosure to avoid derating the breaker itself. Main circuit uses spring-loaded terminals accepting 2x (0.25 to 2.5 mm²) solid or 2x (0.25 to 1.5 mm²) finely stranded with ferrule — no screw torque to check, just strip and push. IP20 on the front; keep it inside a cabinet — this is not a washdown-rated device.","metaTitle":"Siemens 3RV1011-0JA20-ZW95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1011-0JA20-ZW95 motor protection circuit breaker, 1 A rated current, CLASS 10 trip, 100 kA breaking capacity at 400 V.
