The closest functional peer is the 5SL4363-7 — same SENTRON family, same C-curve and 32 A rating, but 3-pole instead of 4. The 5SL4363-7 occupies 3 MW (54 mm wide) and carries a higher 10 kA breaking capacity versus the 6 kA on the 4-pole. If your panel was laid out for the 3-pole version and you need 4-pole protection for a three-phase-plus-neutral feed, the 5SL6432-7 won't drop in without a wider DIN-rail slot — you gain one extra pole width. The 4-pole also dissipates 3.1 W per pole in hot state versus 5 W per pole on the 3-pole version, so total heat in the enclosure is roughly comparable (12.4 W vs 15 W). ## Environmental range and compliance The sealable design allows locking the switch position for lockout/tagout procedures.","metaTitle":"Siemens 5SL6432-7 SENTRON MCB, 4P C 32 A 6 kA","metaDescription":"Siemens SENTRON 5SL6432-7 miniature circuit breaker, 4-pole C-curve 32 A, 6 kA breaking capacity per EN 60898/IEC 60947-2.
