More Details

The FWX-20A14F is a compact high-speed fuse for protecting power semiconductors in low-voltage drives, UPS systems, battery chargers and DC power supplies. Despite what the part number suggests, it's rated 20 amps: the "14F" refers to its 14 x 51 mm ferrule body, which fits standard 14x51 fuse holders and modular DIN-rail bases. As a very fast-acting semiconductor fuse, it clears faults quickly enough to protect diodes, thyristors and transistors that a general-purpose fuse would let fail. It's rated 250 VAC at 200 kA and 250 VDC at 50 kA. Replace with the exact part number the equipment manufacturer specifies. Every fuse we ship is inspected and tested first.

What is "surplus new"?

Surplus new means the item has never been installed or put into service. It may not arrive in its original packaging, but it has never been used.

What does "reconditioned" mean?

Reconditioned items have been inspected, cleaned, and tested to confirm they operate to the manufacturer's original specifications. Every reconditioned item we sell carries a one-year operational guarantee.

How fast will my order ship?

In-stock orders placed before 12pm PST usually ship the same business day via UPS, with tracking provided.
