Product details

The Siemens SENTRON 5SL6632-7MB is a 4-pole (3P+N) miniature circuit breaker rated 400 V AC, 32 A, with a C tripping characteristic and 6 kA breaking capacity per EN 60898 and IEC 60947-2.

Snaps onto standard DIN rail — any mounting position works, which helps when you're retrofitting into a crowded panel.

Key ratings in plain terms

The 32 A rating handles a 7.5 kW three-phase motor at 400 V (roughly) or a cluster of resistive loads up to that line current. Mechanical life is 20,000 cycles typical — that's plenty for a distribution breaker that cycles rarely.

Frequently asked questions

Where can I buy 5SL6632-7MB and how do I get a price?

This part is sourced 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 5SL6632-7MB's listed depth (76 mm) on this component line?

The depth is exactly 76 mm, with an installation depth of 70 mm (the additional 6 mm accounts for the front handle projection). Width is 72 mm (4 modular units), height is 90 mm.

Will 5SL6632-7MB drop into a panel that was specified around 5SL4363-7 without rewiring?

Not without changes. The 5SL4363-7 is a 3-pole breaker (3P) with 10 kA breaking capacity, while the 5SL6632-7MB is 4-pole (3P+N) with 6 kA. The 5SL4363-7 is 3 modular units wide (54 mm), the 5SL6632-7MB is 4 units wide (72 mm), so it won't fit the same DIN-rail footprint without a wider panel or a filler. The neutral pole also means you need a neutral conductor run to the breaker, which the 3-pole version didn't require.
