Product details

The Siemens 5SJ6113-6KS is a SENTRON 5SJ6-series miniature circuit breaker — one pole, B-curve, rated 13 A at 400 V AC, 50 Hz.

Snaps onto DIN rail in a single modular width (18 mm), depth 76 mm, height 90 mm. Sealable design allows lockout/tagout for maintenance isolation. Halogen-free and silicon-free construction avoids corrosive off-gassing in a fire — relevant for data-center or telecom backboards.

Environmental and electrical ratings

Rated insulation voltage (Ui) is 440 V AC; maximum operating voltage in multi-phase operation is 440 V AC. The DC side is rated to 60 V maximum, so it can protect DC control circuits at that level. Mechanical service life is 20 000 switching cycles typical. Touch protection is fitted on the terminals.

Frequently asked questions

What is the breaking capacity of 5SJ6113-6KS?

It is rated 6 kA per both EN 60898 and IEC 60947-2 at 400 V AC. That means it safely interrupts fault currents up to 6 kA in a residential or commercial distribution board.

What is 5SJ6113-6KS's width and how many DIN modules does it take?

It is 18 mm wide — one modular unit on a DIN rail. Depth is 76 mm, height 90 mm.

Where can I buy 5SJ6113-6KS and how is it quoted?

We source and quote it to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price is published here.

Does 5SJ6113-6KS have a direct second-source like 5SL3116-6MB?

The 5SL3116-6MB is a different Siemens series (5SL instead of 5SJ6) with different breaking capacity and terminal design. They are not drop-in replacements without verifying the panel's specified coordination and terminal style. Stick with the 5SJ6 order code for a direct fit.
