The breaker mounts in any position (vertical, horizontal, upside down) and snaps onto standard DIN rail. It occupies 4 modular width units (about 72 mm of rail space). It's also sealable — you can lock the toggle in the off position with a padlock for LOTO compliance. This breaker fits a standard DIN-rail enclosure and is rated for residential buildings and infrastructure (per the suitability listing). It carries IP20 protection with connected conductors — fine inside a closed panel, not for wet or outdoor use without an enclosure. If you're looking at the 5SL3340-7CC as a possible substitute, note the pole count: the 5SL3340-7CC is a 3-pole unit. The 5SL4432-7CC is 4-pole, so it handles three-phase-plus-neutral or a separate switched neutral. The width difference is one modular unit (3 MW vs 4 MW). No rewiring of the panel bus is needed if the original design allowed for the wider footprint, but the neutral pole wiring must be accounted for. ## Sourcing and compliance Compliance documentation — RoHS, REACH, and the IEC/EN standards listed on the nameplate — is available with the shipment.","metaTitle":"Siemens 5SL4432-7CC SENTRON MCB, 4P C 32A 10kA, 400V","metaDescription":"Siemens 5SL4432-7CC SENTRON miniature circuit breaker, 4-pole, C-curve, 32 A rated, 10 kA breaking capacity per EN 60898 at 400 V AC.
