SENTRON 5SN6363-7CP — 3-pole MCB for panel builders
The dual breaking capacity — 6 kA according to EN 60898 and 10 kA per IEC 60947-2 — means it's certified for both residential/commercial branch circuits (EN 60898) and industrial panel applications where higher fault current withstand is required (IEC 60947-2). 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.
