It also carries a 60 V DC maximum rating, so it can protect DC control circuits fed from the same panel. The 63 A rating on a single-pole+N breaker covers high-current branch circuits — think large resistive heaters, lighting banks, or distribution subfeeds where you need overcurrent protection on the live conductor with a switched neutral. Energy limiting class 3 means it restricts let-through energy well, so downstream components see less stress during a short. IP20 with conductors connected, so it belongs inside a closed enclosure, not exposed to washdown. Touch protection is built in. The 1P+N design switches the neutral internally; verify your distribution scheme expects a switched neutral before wiring.","metaTitle":"Siemens 5SJ6563-6 SENTRON MCB, 1P+N, B Curve, 63 A, 6 kA","metaDescription":"Siemens 5SJ6563-6 SENTRON miniature circuit breaker, 1P+N, B characteristic, 63 A, 6 kA breaking capacity per EN 60898. 240 V AC, 60 V DC.
