Product details

The Siemens 5SJ6210-7KS is a 2-pole SENTRON miniature circuit breaker rated 10 A with a C tripping characteristic, breaking 6 kA per EN 60898 and IEC 60947-2 at 400 V AC, 50 Hz. Screwless outgoing terminals speed up panel wiring and reduce torque-check time on the line.

Mounting position is unrestricted — horizontal, vertical, or flat — so it fits tight gland-plate layouts.

Halogen-free and silicon-free construction, sealable for tamper-evident applications. Rated insulation voltage 440 V AC, max operating voltage 440 V AC multi-phase. Mechanical service life 20 000 switching cycles typical.

Frequently asked questions

What are the key ratings for 5SJ6210-7KS?

Rated current 10 A, C-curve, 2-pole, breaking capacity 6 kA at 400 V AC (EN 60898 / IEC 60947-2), rated voltage 400 V AC, 50 Hz, max DC voltage 60 V. Insulation voltage 440 V AC.

Where can I buy 5SJ6210-7KS?

Sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time.

Will 5SJ6210-7KS drop into a panel specified for 5SL6016-7KL?

Both are 2-pole C-curve 10 A MCBs with 6 kA breaking capacity at 400 V and 2 MW width. The 5SJ6210-7KS uses screwless terminals versus the 5SL6016-7KL's screw terminals — the panel cutout and DIN-rail footprint are identical, so no rewiring of the busbar or enclosure is needed. The terminal type is the only practical difference.
