This is the part you spec when a 2-module-width, 63-amp C-curve breaker is called out on the BOM for a residential or infrastructure panel. The 6 kA breaking capacity per EN 60898 tells you it can safely interrupt a fault current up to 6,000 A at 400 V AC; anything above that and the upstream device needs to clear it first. The 2-pole design switches both phase and neutral, and the 2-module-width (36 mm) footprint fits standard DIN-rail distribution boards. The -40 °C to 75 °C operating range covers extreme ambient conditions, and the any mounting position spec gives flexibility in tight enclosures. The sealable design allows padlocking in the OFF position for lockout/tagout.","metaTitle":"Siemens 5SL6263-7MB SENTRON MCB, 2P C 63A, 6kA","metaDescription":"Siemens SENTRON 5SL6263-7MB miniature circuit breaker, 2-pole, C-curve, 63 A, 6 kA per EN 60898.
