Siemens SENTRON 5SL6110-7CC — 1-pole C-curve MCB, 10 A, 6 kA
The Siemens SENTRON 5SL6110-7CC is a 1-pole miniature circuit breaker with a C tripping characteristic, rated 10 A at 230/400 V AC and a breaking capacity of 6 kA according to EN 60898.
For a residential or light-commercial panel with a typical prospective short-circuit current under 6 kA, that is sufficient. The 1-pole design protects a single phase; for 230 V single-phase circuits, the rated voltage is 250 V per pole, and for 400 V three-phase systems, the MCB sees line-to-neutral faults at 230 V. The C-curve is the most common characteristic for general-purpose socket outlets and small-load circuits in Europe — it avoids tripping on the brief inrush of a desk lamp or a small fan motor. In a multi-pole assembly, sum the losses for thermal management inside the enclosure — a 4-pole unit dissipates roughly 6.8 W.
Occupies 1 modular width unit (18 mm). Installation depth behind the panel is 70 mm, with an overall depth of 76 mm including the front projection. Any mounting position is permitted.
