Product details

The 10 kA breaking capacity per EN 60898 covers the vast majority of domestic and light commercial installations; the 20 kA rating per IEC 60947-2 and 15 kA at DC per IEC 60947-2 give headroom for industrial panel SCCR requirements where fault levels are higher. The dual-standard listing (EN 60898-1 / IEC 60947-2 / UL1077) means it carries both a certified MCB mark for distribution boards and an industrial circuit-breaker rating for control-panel use — one part for both worlds.

The 5SY4532-7 occupies 2 modular width units (36 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. The neutral conductor is switched internally, so no separate neutral bar is needed downstream — a space-saver in crowded sub-distribution boards. The combined terminal at top and bottom accepts both busbar and cable, simplifying daisy-chaining.

Frequently asked questions

What are the breaking capacity ratings for 5SY4532-7?

The 5SY4532-7 is rated 10 kA per EN 60898, 20 kA per IEC 60947-2, and 15 kA at DC per IEC 60947-2. It also carries a 5 kA rating per UL 1077 / CSA C22.2 No.235.

Will 5SY4532-7 drop into a panel specified around 5SY4116-7CV without rewiring?

Yes — both are 1P+N, 2-module (36 mm) SENTRON MCBs with the same DIN-rail footprint, terminal arrangement, and C-curve. The 5SY4532-7 carries a higher current rating, so verify the branch circuit ampacity and upstream protection; no mechanical or wiring changes are needed.

Where can I buy 5SY4532-7 and get current pricing?

The 5SY4532-7 is available to order through independent distribution. Submit an RFQ; availability and current pricing are confirmed at quote time.
