The Siemens 5SJ6106-6RC is a SENTRON-series miniature circuit breaker — a single-pole, 6 A unit with a B tripping characteristic. With a 6 kA breaking capacity per EN 60898, it can safely interrupt a 6,000 A fault on a 415 V AC line — enough for most retail or light-commercial subpanels. If you're working a 24 V DC control circuit, it's rated up to 72 V DC, which covers the common industrial control voltages. It's halogen-free and silicon-free, so if your spec calls for low-corrosion materials near sensitive electronics or in a sealed panel, this one checks that box.

Frequently asked questions
What is the 5SJ6106-6RC's depth and width for panel layout?
The width is 18 mm (one modular unit), and the overall depth is 76 mm with an installation depth of 70 mm behind the panel surface. That's standard for a single-pole MCB on DIN rail.
Will the 5SJ6106-6RC replace a 5SL3116-6MB without rewiring?
Yes, both are 1-pole, 18 mm wide, B-curve breakers with the same DIN-rail footprint and terminal layout. The 5SJ offers a higher breaking capacity (6 kA vs 4.5 kA) and drops into the same panel position.
Where can I buy the 5SJ6106-6RC 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 — no online stock figure is shown because supply conditions change daily.
