At 40 °C ambient the continuous rating derates to 59.54 A; at 50 °C it's 55.82 A. The 2 MW width (36 mm) and 76 mm depth fit standard DIN-rail enclosures; quick-assembly fastening and any mounting position simplify panel layout. Vibration resistance per IEC 60068-2-6 (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz) means it holds up on a conveyor drive panel or compressor skid. Pollution degree 3 (conductive or dry non-conductive pollution) suits industrial environments. Halogen-free and silicon-free construction — no corrosive off-gassing in a sealed enclosure. Combined terminal top and bottom, touch-protected, and sealable for lockout/tagout compliance.","metaTitle":"Siemens 5SY7263-8CC SENTRON MCB, D-Curve 63A 2-Pole, 15kA","metaDescription":"Siemens 5SY7263-8CC SENTRON miniature circuit breaker, D-curve, 63A, 2-pole, 15kA IEC breaking capacity.
