MPN5SY3032-7KV

Siemens SENTRON 5SY3032-7KV miniature circuit breaker, C-curve 32A, 4.5kA at 230V AC, 1+N-pole, 1MW, 70mm depth.

Product details

The 1+N-pole design switches both line and neutral, with the neutral pole switching but not protecting — common in single-phase distribution boards where a shared neutral bus isn't used. Installation depth of 70 mm fits standard DIN-rail enclosures.

The C-curve (trips at 5–10× rated current) is sized for motor and transformer inrush loads where a B-curve would nuisance-trip on startup. At 32 A continuous, it protects downstream wiring sized for that ampacity.

Panel Integration

The touch-protected terminals meet finger-probe requirements per VBG 4.

Frequently asked questions

What is 5SY3032-7KV used for?

It's a C-curve miniature circuit breaker rated 32 A at 230 V AC with 4.5 kA breaking capacity, used for branch-circuit protection in residential and light-commercial single-phase distribution boards, particularly where motor or transformer inrush loads are present.

Where can I buy 5SY3032-7KV?

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

Will 5SY3032-7KV drop into a panel specified for 5SY3025-7KL?

Both are SENTRON 1+N-pole MCBs with 70 mm installation depth on standard DIN rail, so the footprint is identical. The main difference is rating: the 5SY3032-7KV is a 32 A C-curve, while the 5SY3025-7KL is a 25 A C-curve. Verify the branch-circuit ampacity requirement before substituting.
