For DC circuits, it's rated up to 72 V. The 5SN6363-7CP occupies 3 modular width units (54 mm wide) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm behind the panel face. Height is 90 mm. It accepts solid conductors up to 35 mm², which covers most feeder and branch circuit wiring in distribution boards. The -40 °C to 75 °C operating range means it's usable in unheated enclosures or outdoor-rated cabinets, though the upper limit is the internal ambient — derate if the enclosure runs hot. ## Electrical performance and duty Power loss is 6 W per pole in hot operating state at rated current — useful to know when calculating thermal rise in a densely populated enclosure.","metaTitle":"Siemens 5SN6363-7CP SENTRON MCB, 3P C-Curve, 6/10 kA","metaDescription":"Siemens 5SN6363-7CP SENTRON 3-pole MCB, C-curve, 400 V AC, 50 Hz.

The main difference is breaking capacity: 5SN6363-7CP is rated 6 kA (EN 60898) / 10 kA (IEC 60947-2), while 5SL4363-7 is rated 10 kA under both standards.
