Product details

Siemens 5SJ6105-7 SENTRON Miniature Circuit Breaker, 1-Pole C 0.5A

The Siemens 5SJ6105-7 is a 1-pole SENTRON miniature circuit breaker with a C-curve trip characteristic rated at 0.5 A and a 6 kA breaking capacity per EN 60898 and IEC 60947-2. The IP20 finger-safe terminals accept wiring with connected conductors.

The 5SJ6105-7 carries a current lifecycle status from Siemens, meaning it remains in the active catalog for new designs and replacement orders. Halogen-free and silicon-free construction meets clean-environment requirements for data centers, medical equipment, or food-processing zones where outgassing must be minimized.

Integration Notes

Single-pole format with touch-protected terminals and sealable option for tamper-proof installations. Rated overvoltage category III, insulation voltage 440 V AC. Mechanical endurance of 20,000 switching cycles typical for the class.

Frequently asked questions

What is the breaking capacity of 5SJ6105-7?

It is rated 6 kA per EN 60898 and IEC 60947-2 at 240 V AC, sufficient for most residential and light commercial sub-circuits.

Where can I buy 5SJ6105-7?

This part is available to order through our distribution channel. Submit an RFQ for a quote on your volume — pricing and lead time confirmed at quote time.

Will 5SJ6105-7 drop into a panel specified around 5SL4120-7CC?

Both are 1-pole SENTRON MCBs with the same 70 mm installation depth and single width unit, so the physical footprint is identical. The key difference is rating: 5SJ6105-7 is 0.5 A C-curve with 6 kA, while 5SL4120-7CC is 20 A C-curve with 10 kA — verify the load current and fault level before substituting.
