Product details

The Siemens SENTRON 5SL3110-7MB is a 1-pole miniature circuit breaker with a C-curve trip characteristic, rated 10 A at 230/400 V AC. IP20 with conductors connected means it belongs inside an enclosure — not exposed to washdown or outdoor weather.

At 10 A rated current, it carries 10 A continuously at 30 °C ambient without nuisance tripping, and the 4.5 kA breaking capacity per EN 60898 means it can safely interrupt a short-circuit fault up to that level. Overvoltage category III (pollution degree 2) qualifies it for fixed-installation distribution boards, not just plug-in equipment.

The 18 mm width (1 MWU) means it occupies one standard slot; plan your busbar and comb distribution accordingly.
