Product details

The Siemens 5SL6106-6MB is a SENTRON miniature circuit breaker — a 1-pole, 6 A, B-curve MCB rated for 6 kA breaking capacity per EN 60898 at 230/400 V AC.

Panel fit and environmental range

The 5SL6106-6MB is 76 mm deep, 18 mm wide, and 90 mm tall, with 70 mm installation depth. Degree of pollution 2 and overvoltage category III are standard for fixed-installation MCBs in distribution boards.

The 6 kA breaking capacity per EN 60898 is the standard rating for residential and light commercial distribution — it can safely interrupt a fault current up to 6 kA at 230/400 V AC without welding its contacts or arcing over. The B-curve's 3–5x In trip threshold means it won't nuisance-trip on the modest inrush of a tungsten lamp bank or a resistive load, but it's not the right choice for motor circuits or transformers — those need a C or D curve.

Frequently asked questions

Where can I buy 5SL6106-6MB and get current pricing?

We source and quote the 5SL6106-6MB to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — send an RFQ for a firm quote.

What are the key specs of 5SL6106-6MB?

It's a 1-pole, B-curve, 6 A miniature circuit breaker with 6 kA breaking capacity per EN 60898 at 230/400 V AC. It occupies 1 modular width (18 mm) on DIN rail, operates from -40 °C to 75 °C, and is rated IP20 with connected conductors.

Will 5SL6106-6MB drop into a panel that was specified around 5SL4363-7?

No — the 5SL4363-7 is a 3-pole, C-curve MCB with 10 kA breaking capacity and occupies 3 modular widths (54 mm). The 5SL6106-6MB is a single-pole, B-curve unit at 18 mm wide. They share the same 76 mm depth and 90 mm height, so the physical envelope is compatible, but the pole count, trip curve, and breaking capacity are different. You'd need to re-evaluate the circuit protection requirements before swapping.
