The Siemens SENTRON 5SL6332-6CC is a 3-pole miniature circuit breaker (MCB) with a B tripping characteristic, rated 32 A at 400 V AC and a breaking capacity of 6 kA according to EN 60898. The 6 kA breaking capacity at 400 V tells you it can safely interrupt a fault current up to 6,000 A without welding contacts or cascading failure upstream — adequate for most final subcircuits in a TN or TT system where the prospective short-circuit current stays under that threshold. Rated for 50/60 Hz supply, the 5SL6332-6CC accepts up to 440 V AC in multi-phase operation.
Width is 54 mm — that's 3 modular width units at 18 mm each, so it occupies three adjacent slots in the distribution board. Depth is 76 mm, installation depth 70 mm; the 90 mm height leaves clearance for most enclosure lids with busbar shrouds. Mounting position is any, which simplifies layout in crowded panels. Sealable design allows tamper-proofing with a lead seal wire through the housing. Vibration resistance tested to 50 m/s² at 25 to 150 Hz per IEC 60068-2-6 — it holds up on machine-mounted sub-distribution near pumps or conveyors.
