The Siemens 5SL6132-8CC is a SENTRON miniature circuit breaker, one pole, D-curve, rated 32 A at 400 V AC. Its 6 kA breaking capacity per EN 60898 covers residential and light commercial fault levels — enough for most final subcircuits in a distribution board, but verify against your upstream transformer impedance if the prospective short-circuit current exceeds that.
DIN-rail fit and panel integration
Width is 18 mm (one width unit), height 90 mm, depth 76 mm — standard 1-MODULE footprint that snaps onto a DIN rail. Installation depth 70 mm behind the panel face. Mounting position any, so horizontal or vertical busbar arrangements work. Terminals accept 0.75 to 25 mm² solid or stranded; torque to 2.5–3 N·m. IP20 with connected conductors, meaning the panel door or enclosure provides the environmental seal.
D-curve trip and load type
D characteristic means magnetic trip between 10× and 20× In — suited for loads with high inrush like small transformers, solenoid valves, or motor starters where a B or C curve would nuisance-trip. Rated for 50 Hz AC only. Single-phase operation at 250 V AC; multi-phase up to 440 V AC. No neutral switching (1P only). Ambient operating range -25 to +45 °C; storage -40 to +75 °C.
