The Siemens 3NJ6314-2AA0.-.... is a SENTRON 3NJ63 switch disconnector with fuses in an in-line, pluggable design. Rated for NH1 fuse links up to 250 A, it switches 4-pole circuits at AC23B duty up to 500 V with a 55 kA rated short-circuit breaking capacity at 500 V AC. The AC23B rating means it is built for switching motor loads — frequent on-off cycles under full load current, not just isolation. This is a category C product: manufactured to order, not stocked as a standard shelf item, and non-returnable once produced. Plan your BOM freeze accordingly — no last-minute swaps.
Lead time depends on the Siemens production schedule at the moment of ordering. We source through independent distribution channels and can provide a firm delivery window with the quotation.
