Product details

It carries a 10 kA breaking capacity per EN 60898-1 and 20 kA per IEC 60947-2, with a 15 kA DC rating under IEC 60947-2 and 5 kA under UL 1077 / CSA C22.2 No.235.

Breaking capacity and standard coverage

This breaker is certified to IEC / EN 60898-1 (domestic and similar installations) and IEC / EN 60947-2 (industrial switchgear), plus UL 1077 for North American supplementary protection. The 20 kA rating under IEC 60947-2 gives headroom for high-fault industrial panels; the 10 kA EN 60898-1 figure covers the more common commercial duty. The DC rating of 15 kA at 60–72 V makes it usable in DC auxiliary circuits, though the AC application is the primary fit.

It mounts in any position and uses a quick-assembly system for rail snap-on.

Environmental and compliance details

Halogen-free and silicon-free construction. Sealable terminals are provided for anti-tamper requirements.

Frequently asked questions

Where can I buy 5SY4132-7 and get current pricing?

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 quote.

What is the breaking capacity of 5SY4132-7?

10 kA per EN 60898-1, 20 kA per IEC 60947-2, 15 kA DC per IEC 60947-2, and 5 kA per UL 1077 / CSA C22.2 No.235.

Will 5SY4132-7 drop into a panel specified around 5SY4140-7?

Both are 1-pole SENTRON MCBs with the same 18 mm width and DIN-rail mounting, so the mechanical fit is identical. The difference is the current rating — 5SY4140-7 is a higher-amperage variant. Verify the load current before substitution.

What compliance documentation does Siemens provide for 5SY4132-7?

The breaker is certified to IEC / EN 60898-1, IEC / EN 60947-2, and UL 1077 / CSA C22.2 No.235. It is halogen-free and silicon-free. Standard Siemens declarations of conformity and UL recognition documentation are available upon request.
