Product details

Breaking capacity is rated 10 kA per IEC/EN 60898-1 and 20 kA per IEC 60947-2, with a further 15 kA at DC per IEC 60947-2. At DC the 15 kA rating applies up to 60 V (72 V max). Neutral is switched (3P+N), which matters for panels where the neutral must be disconnected for isolation — common in industrial machine supply.

Certified to IEC/EN 60898-1 and IEC/EN 60947-2, plus UL 1077 and CSA C22.2 No. 235 (5 kA at AC under those standards). The dual-standard coverage simplifies BOM compliance across regions — the same part number works for a panel built to IEC 61439 or a North American supplementary-protector application. Halogen-free and silicon-free construction, sealable, with energy limitation class 3.

Frequently asked questions

What is the breaking capacity of 5SY4625-6?

10 kA per IEC/EN 60898-1, 20 kA per IEC 60947-2 at 400 V AC, and 15 kA per IEC 60947-2 at 60 V DC. Under UL 1077 it is rated 5 kA at AC.

Will 5SY4625-6 drop into a panel specified around 5SY4304-7CV?

Both are 4-pole SENTRON MCBs on the same DIN-rail quick-assembly system, so the mechanical footprint matches. The deciding difference is the tripping characteristic: 5SY4625-6 is B-curve; 5SY4304-7CV is a different curve variant. Verify the required inrush handling before substituting.

Where can I buy 5SY4625-6?
