COL120-12/RA Partex right-angle copper tube terminal, 120mm², M12 stud, pack 25

Why Choose the Partex COL120-12/RA 120mm² Right-Angle Copper Tube Terminal?

The Partex COL120-12/RA is a heavy-duty 120 mm² right-angle copper tube ring terminal designed to provide secure and reliable electrical connections between large copper conductors and equipment fitted with M12 stud terminals. Featuring a 90° angled mounting palm, this industrial cable lug is particularly suitable for power distribution systems, switchgear and electrical installations where restricted space or cable routing requirements make conventional straight terminals less practical.

As part of the Partex COL right-angle copper tube terminal range, the COL120-12/RA combines robust copper construction with a tubular crimp barrel designed for permanent conductor termination. Its angled ring-shaped mounting palm enables secure attachment to compatible bolted electrical connections, while the copper construction supports efficient electrical current transfer. The right-angle configuration helps installers accommodate larger conductors without introducing unnecessary bends close to the termination point.

Designed for 120 mm² copper cables and an M12 mounting stud, the COL120-12/RA provides a practical termination solution for industrial switchgear, power distribution equipment, heavy-duty electrical machinery and electrical control assemblies. Supplied in a convenient pack of 25 terminals, it is suitable for electrical contractors, panel builders, OEM manufacturers and industrial maintenance engineers requiring dependable large-conductor connections.

Reliable Right-Angle Cable Terminations for Heavy-Duty Power Distribution

Right-angle copper tube terminals such as the Partex COL120-12/RA provide a practical method of connecting large copper conductors to bolted terminals, busbars and industrial power equipment where a straight cable lug may not provide sufficient installation clearance. The angled mounting palm changes the orientation of the connection relative to the cable barrel, enabling more flexible conductor routing inside electrical enclosures.

The heavy-duty tubular barrel is designed to accept a correctly prepared 120 mm² copper conductor, which is secured using an appropriately sized compression crimping tool and die. When correctly installed, the crimped joint provides dependable electrical contact and mechanical retention. The M12 ring-shaped mounting palm is then secured to a compatible stud or bolted electrical connection point.

The 90° terminal configuration is particularly useful when larger conductors must be routed around nearby equipment, connected to busbars or terminated within restricted switchgear compartments. By allowing the cable to approach the mounting point at an angle, the COL120-12/RA can help reduce excessive bending close to the termination and support more organised cable management.

For correct installation, the terminal should be crimped using tooling and dies suitable for the terminal and conductor construction. The bolted connection should be tightened to the equipment manufacturer's specified torque. As the COL120-12/RA is uninsulated, appropriately rated heat-shrink sleeving, insulating boots or protective barriers should be applied where required. The completed termination must be suitable for the circuit current, operating voltage, conductor construction, mechanical loading and environmental conditions. The electrical and mechanical suitability of the M12 connection must also be verified for the intended application.
