AD250012 | Single Insulated Wire Ferrules

Our Single Insulated Wire Ferrules are made of tin plated copper with a colorful polypropylene collar. These ferrules are manufactured in accordance with strict DIN and UL specifications.

What is a wire ferrule? A wire ferrule is a tinned copper sleeve, which is slipped over stranded wire and then crimped. This creates a solid connection for insertion into terminal block housings or various other applications. The crimped ferrule provides a sturdy connection that limits wire fraying and increases the life of the conductor.  Our ferrules are sold in packages, strips, and also in reel form.

Insulated or Non-Insulated Wiring Ferrules’ Suitable Use
Any manufacturer’s ferrules are suitable for use provided they are:

 

A. For use in factory wiring only, power or control circuits.
B. Crimped with an appropriate tool as recommended by the ferrule manufacturer before terminating in terminal blocks, wire connectors, or end-product terminals (such as starters, etc.).
C. Sized in diameter appropriate for the number of wires, wire type (stranded/solid) and wire size as recommended by the ferrule manufacturer such that the crimp results in a reliable connection.
D.  Constructed such that the length of the wires held captive by the ferrules are trimmed, if necessary, and that there are no excess live parts, which can result in the reduction of electrical spacings.
