Product details

IP20 with connected conductors is the norm for enclosed distribution boards — no special sealing needed inside a dry indoor panel.

The 5SL4 design is the standard SENTRON miniature breaker platform. If you're cross-referencing an older 5SL3 or a different brand's D-curve 32 A 1P, the 5SL4132-8 drops into the same DIN footprint and busbar pitch. No rewiring or busbar modification needed — same 18 mm module width, same terminal layout.

Touch protection is built in — no live parts exposed when the breaker is installed in a distribution board with the cover closed. That's adequate for a distribution board where the breaker operates rarely (fault protection, not daily switching). If you need frequent on-load switching, a contactor or disconnect switch would be the better choice.

Frequently asked questions

What is the closest functional second-source to 5SL4132-8?

The 5SL3120-6MB is a 1-pole D-curve breaker but rated 20 A, not 32 A. It shares the same 18 mm width, DIN-rail mount, and 10 kA breaking capacity, so it's a drop-in for the same panel footprint if you need a lower current rating. For a 32 A replacement, stick with the 5SL4132-8 or a same-rating alternative from another brand.

Where can I buy 5SL4132-8 and get current pricing?

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 compliance documentation does Siemens provide for 5SL4132-8?

The breaker is rated per EN 60898 and IEC 60947-2 for breaking capacity, and carries the SENTRON brand's standard CE marking for the European market. Halogen-free and silicon-free construction is documented. For specific RoHS/REACH declarations or UL listing files, request the manufacturer's compliance documentation with your RFQ.
