Product details

The 5SL3632-7 is a 4-pole (3P+N) miniature circuit breaker from the Siemens SENTRON 5SL3 family, rated 32 A at 400 V AC with a C-curve trip characteristic. The 4.5 kA breaking capacity per EN 60898 and IEC 60947-2 is the fault current it can safely interrupt at 400 V; for most residential and light commercial panels this is adequate, but verify the prospective short-circuit current at the installation point.

Panel integration and physical fit

The IP20 rating applies only with connected conductors — the busbar and wiring must be in place to maintain the finger-safe enclosure. Terminal touch protection is included per the product feature.

The overvoltage category is 3 and pollution degree 2 — typical for fixed-installation distribution boards. The part carries the SENTRON brand designation and is classified per IEC 81346-2 and DIN EN 61346-2 as function F (circuit protection).

Frequently asked questions

What is the breaking capacity of the 5SL3632-7?

The breaking capacity is 4.5 kA at 400 V AC, rated per both EN 60898 and IEC 60947-2.

Where can I buy the 5SL3632-7 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the physical size of the 5SL3632-7?

Width is 72 mm (4 modular units), depth is 76 mm, height is 90 mm. Installation depth is 70 mm.

Will the 5SL3632-7 drop into a panel specified for the 5SL3640-7MB?

Both are 4-pole SENTRON 5SL3 series MCBs on the same DIN-rail footprint, so the mechanical fit is identical. The difference is the rating: the 5SL3632-7 is a 32 A C-curve, while the 5SL3640-7MB is a 40 A unit. Verify the load current and cable sizing before substitution.
