It occupies a single 18 mm modular width on the DIN rail, with a depth of 76 mm and an installation depth of 70 mm. The 6 kA rating under EN 60898 is the standard for residential and light commercial distribution boards — it tells you the breaker can safely interrupt a fault current up to 6 kA at its rated voltage without welding or arcing over. The 10 kA rating under IEC 60947-2 is the industrial counterpart, used when the prospective short-circuit current at the breaker's location exceeds 6 kA. Single modular width (18 mm) means it replaces any 1-pole MCB in the same footprint without re-drilling the rail or moving adjacent devices. The terminal accepts solid conductors up to 35 mm² — oversized for a 16 A or 20 A circuit, but useful when you're looping through a busbar or feeding a downstream sub-panel. Depth of 76 mm plus the 70 mm installation depth leaves about 6 mm behind the DIN rail for wiring channels; check your enclosure's internal clearance if you're mounting it in a shallow gland plate.","metaTitle":"Siemens 5SN6163-8CP SENTRON MCB, 1-Pole, 400 V AC, 6 kA","metaDescription":"Siemens 5SN6163-8CP SENTRON miniature circuit breaker, 1-pole, 400 V AC, 6 kA per EN 60898, 10 kA per IEC 60947-2. 18 mm wide, -40 to 75 °C.

The 5SN6163-8CP has a higher breaking capacity (6 kA vs 4.5 kA per EN 60898) and a wider operating temperature range (-40 °C to 75 °C vs -40 °C to 75 °C, same).
