Product details

It is rated 10 kA breaking capacity per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC, with a DC rating of 60 V. The 70 mm depth is a standard panel depth; no special enclosure clearance needed.

Ratings and their meaning for the buyer

The 15 kA rating under IEC 60947-2 gives headroom for industrial distribution boards with higher fault levels — the higher standard certifies the breaker for use as a branch-circuit protective device in motor starter combinations. The D-curve trips magnetically between 10× and 20× In, so it holds through motor starting current without nuisance trips. Overvoltage category 3 and pollution degree 3 mean it is rated for fixed-installation distribution panels, not plug-in portable equipment.

Frequently asked questions

How do I get current pricing and availability for 5SJ4202-8HG41?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time through independent distribution channels.

Will 5SJ4202-8HG41 drop into a panel specified around 5SY4140-7 without rewiring?

Both are 2-pole DIN-rail MCBs in the same SENTRON family, but verify the tripping characteristic and breaking capacity against your design. The 5SJ4202-8HG41 is a D-curve rated 10 kA (EN 60898) / 15 kA (IEC 60947-2); the 5SY4140-7 is a different curve and rating. The physical footprint (36 mm wide, 70 mm deep) and DIN-rail mounting are the same, so it will mechanically fit without panel modification, but the electrical protection coordination must be reviewed.

What compliance documentation does this brand provide for 5SJ4202-8HG41?

As a Siemens SENTRON product, it carries CE marking and is designed to EN 60898 and IEC 60947-2. RoHS and REACH compliance documentation is standard for the series. The part is halogen-free and silicon-free.
