Each pole dissipates 4.4 W in hot operating state, which matters for thermal fill calculations in a crowded DIN-rail enclosure. ## DIN-rail footprint and modular width At 36 mm wide (2 modular units), the 5SL6263-7RC snaps onto standard 35 mm DIN rail and occupies two 18 mm slots. Mounting position is unrestricted — vertical, horizontal, or inverted — so panel layout is flexible. The IP20 rating applies with connected conductors, meaning the busbar stabs and terminals are finger-safe once wired; treat the front face as touch-safe during commissioning. ## Expansion and environmental range Operating temperature span is -40 to 75 °C, covering unheated utility rooms and outdoor-adjacent enclosures.","metaTitle":"Siemens 5SL6263-7RC SENTRON MCB, 63 A, 2-pole, C-curve, 7.5","metaDescription":"Siemens 5SL6263-7RC SENTRON miniature circuit breaker, 63 A, 2-pole, C characteristic, 7.5 kA breaking capacity per EN 60898.
