It carries dual breaking-capacity ratings: 6 kA according to EN 60898 for residential/commercial branch circuits, and 15 kA per IEC 60947-2 for industrial panel applications — the higher figure governs fault-clearing capability in a 400 V distribution board where through-fault current can exceed 10 kA. The 76 mm depth, 54 mm width, and 90 mm height occupy 3 modular width units on a DIN rail, with an installation depth of 70 mm. Solid conductors up to 35 mm² terminate in the box clamp, which handles the incoming feed for a 3-phase sub-distribution board without a separate terminal block. ## Voltage range and environmental limits Multi-phase and single-phase operation at AC is rated to 440 V maximum. DC operation is limited to 72 V maximum.","metaTitle":"Siemens 5SN6310-7CP MCB 5SN, 3-pole C-curve, 400 V AC, 6/15","metaDescription":"Siemens 5SN6310-7CP MCB 5SN, 3-pole, C-curve, 400 V AC, 6 kA (EN 60898) / 15 kA (IEC 60947-2).
