The Siemens SENTRON 5SL4132-7CC is a 1-pole miniature circuit breaker (MCB) with a C tripping characteristic, rated 32 A at 230/400 V AC. Its 10 kA breaking capacity per EN 60898 covers most residential and light commercial distribution boards — enough to handle a typical utility-side fault current without upstream coordination issues.
What the ratings mean for fit
The C-curve (5–10× In) means it tolerates moderate inrush — think lighting banks, small motors, or capacitor loads — without nuisance tripping. At 32 A it feeds a 7 kW resistive load or a 4 kW motor circuit comfortably. The 10 kA breaking capacity per EN 60898 is the standard for final circuits in buildings; it safely interrupts a short-circuit fault up to that level without welding contacts or cascading damage. Width is 18 mm (one modular unit), depth 76 mm — fits any standard 35 mm DIN-rail enclosure. The 70 mm installation depth leaves room behind the busbar in shallow consumer units.
Where it is used
Designed for residential buildings and infrastructure — final subcircuits in distribution boards, lighting, socket outlets, and small appliance feeds. The IP20 rating (with connected conductors) suits dry indoor enclosures.
