63 A, C-curve, 2-pole — panel fit and breaking capacity
Rated voltage is 250 V single-phase or 415/440 V multi-phase AC at 50/60 Hz, so it works on single-pole 230/240 V circuits or across two phases in a 400 V three-phase panel. 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.
