The Siemens SENTRON 5SL6410-6RC is a 4-pole miniature circuit breaker (MCB) rated 10 A with a B tripping characteristic and a 7.5 kA breaking capacity per EN 60898. Rated at 10 A continuous at 30 °C ambient, it handles the usual 2.5 mm² copper circuit for socket outlets or fixed lighting. Maximum operating voltage is 440 V AC in multi-phase operation, so it sits comfortably on 400/415 V three-phase networks. Frequency range is 50/60 Hz, covering both common mains standards.
It occupies 4 modular width units at 72 mm wide, so plan for 4 x 18 mm slots in your distribution board. Mounting position is any — horizontal, vertical, or flat — so no restrictions on how you orient the board. Supplementary devices like shunt trips or auxiliary contacts can be added, which is handy if you need remote tripping or status feedback without replacing the breaker. Sealable for lockout/tagout, so you can padlock the toggle in the off position for maintenance isolation.
