Product details

The Siemens SENTRON 5SY6310-6CC is a 3-pole miniature circuit breaker with a B tripping characteristic, rated 6 kA breaking capacity per EN 60898 at 400 V AC. It also carries a UL 1077 / CSA C22.2 No.235 rating of 5 kA, so it clears faults in both IEC and North American panels without needing a separate interrupting rating callout.

The B-curve (3–5× In magnetic trip) suits resistive and general-purpose loads — lighting banks, small transformers, control circuits — where inrush stays moderate.

Integration notes

Sealable top and bottom combined terminals allow padlocking for lockout/tagout. Halogen-free and silicon-free construction avoids corrosion risk in sealed cabinets near sensitive electronics.
