UCEF412 Partex uninsulated cord end ferrule, 4mm², 12mm barrel

Why Choose the Partex UCEF412 Uninsulated Cord End Ferrule?

The Partex UCEF412 is a professional uninsulated cord end ferrule designed for terminating flexible stranded copper conductors with a nominal cross-sectional area of 4 mm². Featuring a 12 mm metal barrel length, this bootlace ferrule provides a practical solution for preparing conductor ends before insertion into compatible electrical terminals, helping achieve neat, consistent and professionally finished wiring connections.

Part of the Partex UCEF uninsulated cord end ferrule range, the UCEF412 is designed to consolidate individual copper strands into a compact crimped termination. Its collar-free construction makes it suitable for applications where an uninsulated ferrule is preferred or specified, including electrical control panels, industrial machinery and power distribution equipment.

The combination of a 4 mm² conductor capacity and 12 mm barrel length makes the UCEF412 a practical choice for electrical installers, panel builders and maintenance engineers. When installed using a suitable ferrule crimping tool, it helps prevent stray conductor strands, supports consistent conductor preparation and facilitates insertion into appropriately sized electrical terminals.

Reliable Uninsulated Conductor Terminations for Industrial Electrical Installations

Correct preparation of flexible stranded conductors is important for achieving consistent electrical connections. The Partex UCEF412 uninsulated cord end ferrule provides a practical method of preparing 4 mm² copper conductors for connection to compatible electrical terminals. Its crimpable metal barrel helps consolidate individual conductor strands, creating a compact termination that can be inserted into an appropriately sized terminal opening.

Unlike insulated cord end ferrules, the UCEF412 does not incorporate a plastic entry collar. This uninsulated design can be useful where installation space is restricted or where the terminal manufacturer specifies a collar-free ferrule. However, the ferrule itself does not provide additional electrical insulation, so the completed installation must maintain the required clearances, insulation and protection against accidental contact.

During installation, the conductor should be stripped to a length appropriate for the 12 mm barrel and the receiving terminal's requirements. The exposed copper strands are inserted fully into the ferrule before the barrel is compressed using a compatible crimping tool. A correctly formed crimp helps retain the strands and produces a consistent conductor end for terminal insertion.

The receiving terminal must be suitable for a 4 mm² conductor fitted with an uninsulated ferrule of the resulting crimped dimensions. Installers should follow the terminal manufacturer's instructions regarding ferrule suitability, insertion depth, conductor preparation and tightening torque where applicable. The ferrule does not increase the current-carrying capacity of the conductor or the electrical rating of the terminal.

The Partex UCEF412 is particularly useful for electrical panel builders, machinery manufacturers and industrial maintenance engineers requiring repeatable conductor preparation across control equipment, terminal assemblies and electrical distribution installations.
