Product details

The Siemens 5SJ6313-6KS is a SENTRON 5SJ6 miniature circuit breaker (MCB) — 3-pole, B-curve tripping characteristic, rated 13 A at 400 V AC, with a 6 kA breaking capacity certified to both EN 60898 and IEC 60947-2. Rated for 440 V AC maximum in multi-phase operation and 60 V DC maximum, with an insulation voltage (Ui) of 440 V AC. The 6 kA interrupting rating is the same under both product standards — no derating needed between EN 60898 and IEC 60947-2 applications.

IP20 with connected conductors, pollution degree 2, overvoltage category III. Sealable for tamper-proof installations. Touch protection is built in. Mechanical service life is rated at 20 000 switching cycles typical.

Frequently asked questions

Where can I buy 5SJ6313-6KS and get a price?

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

What does the B-curve characteristic mean for this breaker?

B curve trips at 3 to 5 times rated current (39 A to 65 A for this 13 A unit), making it suitable for resistive loads and general-purpose circuits where inrush is low — typical for lighting, socket outlets, and small appliances in residential or commercial panels.

What is the breaking capacity of 5SJ6313-6KS?

6 kA under both EN 60898 and IEC 60947-2 at 400 V AC. No derating between the two standards for this part.

What compliance documentation is available for this MCB?

The part carries approvals under EN 60898 and IEC 60947-2 for breaking capacity, and is rated for pollution degree 2 and overvoltage category III. It is halogen-free and silicon-free. Specific RoHS/REACH/UL documentation should be requested at quote time.
