COL25-10/RA Partex right-angle copper tube terminal, 25mm², M10 stud, pack 50

Why Choose the Partex COL25-10/RA 25mm² Right-Angle Copper Tube Terminal?

The Partex COL25-10/RA is a high-quality 25 mm² right-angle copper tube terminal designed to provide secure and reliable electrical connections between copper conductors and equipment fitted with M10 stud terminals. Its distinctive 90° angled mounting palm makes it particularly suitable for electrical installations where restricted space, cable routing requirements or equipment configuration make conventional straight cable lugs impractical.

As part of the Partex copper tube terminal range, the COL25-10/RA combines robust copper construction with a practical right-angle design for professional electrical cable termination. The tubular crimp barrel is designed to provide dependable mechanical and electrical contact when installed using suitable crimping equipment, while the angled ring-shaped palm enables secure attachment to compatible bolted electrical connections.

Designed for 25 mm² copper cables and an M10 mounting stud, the COL25-10/RA is ideal for industrial control panels, power distribution equipment, switchgear assemblies and electrical machinery. Its angled configuration helps simplify cable routing and reduce the need for tight conductor bends near termination points. Supplied in a convenient pack of 50 terminals, it provides a practical solution for electrical contractors, panel builders, OEM manufacturers and industrial maintenance engineers.

Reliable Right-Angle Cable Terminations for Industrial Power Distribution

Right-angle copper tube terminals such as the Partex COL25-10/RA provide a practical method of connecting electrical conductors to bolted terminals, busbars and industrial equipment where a straight cable lug may not offer the required installation clearance. The angled mounting palm changes the direction of the connection relative to the cable barrel, helping installers achieve more efficient cable routing within restricted electrical enclosures.

The tubular barrel is designed to accept a prepared 25 mm² copper conductor, which is secured using an appropriately sized crimping tool and die. When correctly installed, the crimped joint provides a permanent mechanical connection and dependable electrical contact. The M10 ring-shaped mounting palm is then secured to a compatible stud or bolted electrical connection point.

The 90° terminal configuration is particularly useful in industrial switchgear, distribution panels and machinery where cable entry direction or nearby components limit the available installation space. By allowing the conductor to approach the fixing point at an angle, the COL25-10/RA can help reduce excessive bending close to the termination and improve cable management.

For correct installation, the terminal must be crimped using suitable tooling and secured with the tightening torque specified for the equipment connection. As the COL25-10/RA is uninsulated, suitable heat-shrink sleeving, insulating boots or protective barriers should be applied where required. The completed connection must be appropriate for the circuit current, operating voltage, conductor construction and environmental conditions.

Typical Applications

• Industrial electrical control panels and switchgear assemblies.
• Power distribution boards and electrical distribution equipment.
• Busbar connections and bolted electrical terminals.
• Electrical installations with restricted cable termination space.
• Industrial machinery and automation systems.
• Motor control centres and associated power equipment.
• OEM electrical equipment manufacturing and panel building.
• Power cable terminations requiring a right-angle connection.
• Electrical maintenance, cable replacement and equipment refurbishment.
• Industrial electrical systems requiring secure 25 mm² copper cable connections to M10 studs.
