The Siemens 5SL4532-6CC is a 1+N-pole miniature circuit breaker rated 32 A with a B tripping characteristic, designed for 230 V AC systems and a 10 kA breaking capacity. It belongs to the 5SL4 Basic Devices family, a standard DIN-rail mounted MCB line for final distribution in residential and light commercial panels.
What the ratings mean for fit
The B-curve trips between 3 and 5 times rated current (96–160 A magnetic release), making it the right choice for resistive and general-purpose loads where inrush is modest — lighting circuits, socket outlets, and control transformers. The 10 kA breaking capacity at 230 V means it can safely interrupt a short-circuit fault up to that prospective level without welding contacts or cascading failure upstream. The 1+N-pole format switches both line and neutral, with the neutral pole switching but not protecting — common in single-phase final circuits where neutral isolation is required.
Panel integration
Snap-on mounting to 35 mm DIN rail per EN 60715. The 1+N-pole module occupies two 18 mm width units. Wire termination accepts up to 25 mm² for line and load side; torque to 2.5–3.0 Nm per the terminal marking. When derating for ambient temperature above 40 °C, apply the standard IEC 60898-1 derating curve for B-curve MCBs.
