The Siemens SENTRON 5SL6105-7BB is a 1-pole miniature circuit breaker with C-curve tripping characteristic, rated 0.5 A at 400 V AC. Its 6 kA breaking capacity is certified under both EN 60898 and IEC 60947-2, so it handles fault currents up to that level in residential and infrastructure branch circuits without upstream coordination issues.
At 18 mm wide (1 width unit) and 76 mm deep, this MCB snaps onto standard DIN rail and leaves 70 mm installation depth behind the panel surface. Mounting position is unrestricted — vertical, horizontal, or inverted — which simplifies layout in crowded enclosures. The IP20 rating applies with connected conductors, typical for protected indoor panels.
