The Siemens SENTRON 5SY5116-7 is a 1-pole miniature circuit breaker with C-curve tripping characteristic, rated 10 kA breaking capacity per IEC/EN 60898-2 and also listed to UL1077. That dual standard (IEC/EN 60898-2 + UL1077) means it's accepted in both European and North American panels — one part number for global BOMs.
Depth of 76 mm with 70 mm installation depth means it clears most shallow enclosures. Mount in any position; IP20 with connected conductors is fine for enclosed panels but not for wet areas. Sealable — you can lock the toggle to prevent unauthorized reset on a critical line.
