Rated supply voltage is 400 V AC at 50 Hz, with a maximum operating voltage of 440 V AC for multi-phase operation. The C-curve tripping characteristic means it handles moderate inrush currents typical of motor and lighting loads without nuisance tripping. Breaking capacity is rated at 6 kA according to EN 60898 and 15 kA according to IEC 60947-2 — the higher IEC figure applies when the breaker is used in industrial distribution where fault currents are larger. For DC circuits, the maximum rated voltage is 72 V. ## Integration notes Dimensions are 90 mm height, 54 mm width, 76 mm depth with a 70 mm installation depth behind the panel. The breaker accepts solid conductors up to 35 mm², which covers most downstream feeder and branch wiring.","metaTitle":"Siemens 5SN6325-8CP MCB, 3-Pole, 6kA/15kA, C-Curve","metaDescription":"Siemens 5SN6325-8CP SENTRON MCB, 3-pole, 400V AC, C-curve, 6kA per EN 60898 / 15kA per IEC 60947-2.
