Breaking capacity is rated at 6 kA according to EN 60898 and 10 kA according to IEC 60947-2 — the higher figure applies when the breaker is installed per the industrial standard, giving selectivity headroom for downstream faults in a plant environment. Rated for multi-phase operation up to 440 V AC maximum, at 50 Hz. The 2-pole configuration suits single-phase 230 V line/neutral or two-phase 400 V line/line circuits where both conductors need overcurrent protection. Depth of 76 mm (installation depth 70 mm) and height of 90 mm — standard SENTRON 5SN envelope. The 36 mm width (2 MW) clips onto a 35 mm DIN rail. Solid conductors up to 35 mm² terminate directly; no adapter needed for the line or load side.","metaTitle":"Siemens 5SN6263-8CP SENTRON MCB, 2-pole C-curve, 6/10 kA","metaDescription":"Siemens 5SN6263-8CP SENTRON 2-pole miniature circuit breaker, C-curve, 400 V AC, 6 kA (EN 60898) / 10 kA (IEC 60947-2).
