Product details

4-pole 32 A C-curve MCB for distribution boards

Rated for 400 V AC multi-phase operation (440 V maximum). C-curve suits mixed loads in residential and infrastructure installations.

Occupying 4 modular width units (72 mm) on a DIN rail, with a 70 mm installation depth and 76 mm overall depth, the 5SL4432-7 fits standard distribution boards and sub-distribution panels. Mounting position is unrestricted — vertical, horizontal, or inverted — which simplifies layout in tight enclosures. Sealable with a lead or wire seal to prevent tampering after commissioning.

Frequently asked questions

Will 5SL4432-7 drop into a panel specified around 5SL4363-7 without rewiring?

No — the 5SL4432-7 is a 4-pole unit (72 mm wide, 4 MW), while the 5SL4363-7 is a 3-pole unit (54 mm wide, 3 MW). The panel's DIN-rail space and wiring scheme differ; you cannot simply swap one for the other without adding a pole and adjusting the busbar arrangement.
