About Uninsulated Bootlace Ferrules

An uninsulated bootlace ferrule (also called an uninsulated end sleeve or cord end terminal) is a bare copper sleeve crimped onto the end of a stranded conductor — serving the same purpose as an insulated ferrule but without the plastic collar. The sleeve consolidates all conductor strands into a single rigid pin that inserts cleanly and securely into a screw terminal, preventing strand splaying, strand breakage under the screw, and stray strands that can cause short circuits.

Uninsulated ferrules have a lower overall profile than insulated ferrules — the absence of the plastic collar means the ferrule body is thinner and shorter at the terminal entry point. This makes them suited to space-restricted terminal blocks where an insulated collar would not fit within the terminal opening, or to installations where colour-coded insulation is not required or where terminal manufacturers specify uninsulated ferrules.

The UBL040L is the long-pin version of the UBL040 — both suit 4.0mm² conductors, but the UBL040L provides an 18mm pin for applications requiring deeper insertion depth versus the 10mm pin of the UBL040. The UBL040L conforms to DIN 46228/1 and is supplied by Pacific Components.

Q: What is the difference between UBL040 and UBL040L?
A: Both suit 4.0mm² conductors as uninsulated bare copper ferrules. The UBL040 has a 10mm pin; the UBL040L has an 18mm pin. Select based on the insertion depth required by the terminal block.

Q: What wire size does the UBL040L suit?
A: The UBL040L suits 4.0mm² stranded conductors — used in power wiring, motor control, and heavier duty switchboard and automation applications.

Q: What tool is required to crimp the UBL040L?
A: A standard bootlace ferrule ratchet crimping tool is required. The tool must have a die set that accommodates 4.0mm² uninsulated ferrules.

Q: How many ferrules are in a pack?
A: The UBL040L is sold in a pack of 100 ferrules.
