Product details

It carries a B tripping characteristic and a 10 A rated current at 230 V AC, with a 6 kA breaking capacity certified to both EN 60898 and IEC 60947-2.

B-Curve Tripping and Breaking Capacity

It avoids nuisance tripping on moderate motor-start currents while still clearing a hard fault within the 6 kA interrupting rating.

At 36 mm wide (2 MW), this breaker occupies two adjacent DIN slots. Mounting position is unrestricted, and the IP20 rating (with conductors connected) is typical for enclosed distribution boards.

The 5SJ6510-6KS is an active, current-production item in the SENTRON portfolio. No last-time-buy or phase-out notice is recorded.

Frequently asked questions

What is the breaking capacity of 5SJ6510-6KS?

It is rated 6 kA per both EN 60898 and IEC 60947-2 at 230 V AC.

What is the width and depth of 5SJ6510-6KS?

The width is 36 mm (2 modular units) and the depth is 76 mm, with a 70 mm installation depth.

Will 5SJ6510-6KS drop into a panel specified around 5SL6016-7KL without rewiring?

The 5SL6016-7KL is 18 mm wide (1 MW) with a C curve and 16 A rating; the 5SJ6510-6KS is 36 mm wide (2 MW) with a B curve and 10 A rating. It will physically mount on the same DIN rail but occupies an extra slot and has different tripping characteristics — verify the branch-circuit load and coordination before substitution.

Where can I buy 5SJ6510-6KS and get current pricing?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
