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.","metaTitle":"Siemens 5SL6106-6MB SENTRON MCB, 1-Pole B 6A 6kA","metaDescription":"Siemens 5SL6106-6MB SENTRON miniature circuit breaker, 1-pole, B-curve, 6 A, 6 kA breaking capacity per EN 60898.

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.
