Product details

The same part also carries a 5 kA rating per UL 1077, so it qualifies for North American supplementary protection duty.

IP20 with conductors connected, so it lives inside a closed enclosure.

Halogen-free and silicon-free construction. Rated for ambient temperatures from -40 °C to 75 °C, with humidity derating above 55 °C (95% RH to 55 °C, 55% to 70 °C, 35% to 75 °C). Pollution degree 3, overvoltage category III. Sealable for lockout/tagout. Meets IEC/EN 60898-1 and IEC/EN 60947-2, plus UL 1077 and CSA C22.2 No. 235.

Frequently asked questions

What is the breaking capacity of 5SY6210-6?

6 kA per EN 60898-1, 15 kA per IEC 60947-2, and 5 kA per UL 1077 — so it covers domestic, industrial, and North American supplementary protection duty from the same unit.

Will 5SY6210-6 drop into a panel specified around 5SY4140-7?

Both are 2-pole SENTRON MCBs on the same DIN-rail footprint, so the mechanical fit is identical. The difference is electrical: 5SY6210-6 carries a B curve and dual 6 kA / 15 kA breaking capacity, while 5SY4140-7 is a different rating within the same family. Check the specific current rating and characteristic on your BOM before swapping.

Where can I buy 5SY6210-6?
