Product details

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.

Frequently asked questions

What is the breaking capacity of 5SN6363-7CP?

It's dual-rated: 6 kA per EN 60898 and 10 kA per IEC 60947-2 at 400 V AC.

Where can I buy 5SN6363-7CP and what is the lead time?

This part is sourced and quoted to order against an RFQ through independent distribution. Current pricing and availability are confirmed at quote time.

Will 5SN6363-7CP drop into a panel specified for 5SL4363-7?

Both share the same 54 mm width, 76 mm depth, 70 mm installation depth, and 90 mm height, so the physical footprint is identical. 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. If your panel requires 10 kA per EN 60898, the 5SL4363-7 is the correct fit; otherwise the 5SN6363-7CP is a drop-in replacement.
