At 32 A it handles a 7.5 kW motor on 400 V three-phase with headroom for the magnetizing inrush. The 3P+N configuration switches the neutral as well as the three phases — the neutral pole is switched, not solid. That matters for TN-S or TT systems where you want guaranteed isolation on all four conductors during maintenance. The 4-pole body occupies 3 width units on the DIN rail, so it fits the same footprint as a standard 3-pole plus one spare module. ## Panel integration and environment IP20 rated, so it belongs inside a closed panel or enclosure, not in a washdown zone.","metaTitle":"SENTRON 5SQ3670-1BA32 MCB, 4P, C-Curve, 32 A, 3 kA","metaDescription":"SENTRON 5SQ3670-1BA32 4-pole MCB, 32 A, C-trip curve, 3 kA per EN 60898, 400 V AC.

The part is sourced to order through independent distribution; availability and current pricing are confirmed at quote time."},{"question":"What does 3P+N mean on this breaker?","answer":"Three protected poles for the phases plus a switched neutral pole — all four conductors are isolated when the breaker is off. The neutral is not solid; it opens with the phases."},{"question":"Will 5SQ3670-1BA32 drop into a panel specified around 5SQ2670-0KA15?","answer":"Both are 4-pole SENTRON 5SQ breakers with the same 55 mm depth, IP20, and DIN-rail mount.
