The 10 kA rating at 72 V DC tells you the internal arc chamber is designed for that. ## Panel fit and environmental tolerance IP20 with connected conductors — that's the standard for enclosed distribution boards. Not a washdown part, but fine inside a weatherproof cabinet. Installation depth is 70 mm (the can depth behind the DIN rail), so plan for at least that plus wiring bend radius. The sealable feature means you can lock the toggle in the off position for lockout/tagout — a plus for maintenance crews who need to verify isolation. ## Sourcing and RFQ posture This is a current-production Siemens SENTRON breaker, widely specified in European-origin distribution boards. Because it's active, the supply channel is the normal distribution network — no need to broker surplus or chase last-time-buy windows. If your BOM calls for the 5SL5263-6CC, it's a straightforward line item with no lifecycle risk.","metaTitle":"Siemens 5SL5263-6CC SENTRON MCB, 2P B63, DC 10 kA","metaDescription":"Siemens SENTRON 5SL5263-6CC miniature circuit breaker, 2-pole, B-curve, 63 A, DC 72 V, 10 kA breaking capacity.
