The Siemens 5SL4532-7CC is a SENTRON miniature circuit breaker (MCB) with a 1P+N pole design, C tripping characteristic, and a 32 A rated current. It breaks fault currents up to 10 kA per EN 60898 at 230 V AC — that's the standard residential and light-commercial fault level, so it coordinates with downstream wiring and upstream distribution boards without needing a higher-rated device.
What the ratings mean for fit
The C-curve means the magnetic trip activates at 5 to 10 times rated current — 160 to 320 A for this 32 A unit. That's sized for mixed resistive and moderate inductive loads like lighting circuits, small appliance groups, and general-purpose socket outlets where inrush isn't severe. The 10 kA breaking capacity at 230 V AC is the standard domestic and commercial fault level per EN 60898; it safely interrupts a short-circuit up to that current without welding contacts or cascading failure upstream. The 1P+N configuration switches the line conductor and provides a switched neutral — the neutral pole opens and closes with the line, which is required in some regional wiring codes and simplifies isolation for the downstream circuit. Occupies 2 modular width units on a DIN rail, so it takes up two 18 mm slots in a standard distribution board.
Where it goes in the panel
Snaps onto a 35 mm DIN rail in any mounting position. The IP20 rating with connected conductors means it's protected against finger contact but not moisture — fit it inside a closed distribution board or enclosure, not in a wet location. Accepts supplementary devices like shunt trips or auxiliary contacts for remote status monitoring. Depth of 76 mm and width of 36 mm — that's a standard two-module footprint. Installation depth of 70 mm leaves clearance behind the DIN rail for wiring. Rated for ambient temperatures from -40 °C to 75 °C, so it handles unconditioned enclosures in cold storage or rooftop installations without derating.
