Product details

Motor protection circuit breaker for 400 V distribution

Rated breaking capacity hits 100 kA at 400 V AC, 500 V AC, and 690 V AC — that SCCR covers most industrial distribution panels without needing an upstream current-limiting fuse.

Fastens via screw or snap-on onto 35 mm standard mounting rail per DIN EN 60715 — same footprint as the rest of the SIRIUS 3RV2 family, so a panel laid out for a 3RV1011 will accept this breaker without drilling new holes. Main circuit connections use spring-loaded terminals accepting 2x (0.5... 2.5 mm²) solid or stranded — no screw torque to verify, just strip and push. Dimensions are 97 mm deep, 45 mm wide, 119 mm high; mounting position is any, which simplifies cabinet layout when space is tight.
