Why Choose the Partex COL150-12/RA 150mm² Right-Angle Copper Tube Terminal?
The Partex COL150-12/RA is a heavy-duty 150 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, electrical switchgear and heavy-duty electrical equipment where restricted installation space or cable routing requirements make conventional straight terminals less practical.
As part of the Partex COL right-angle copper tube terminal range, the COL150-12/RA combines robust copper construction with a tubular crimp barrel designed for permanent compression termination. Its closed ring-shaped mounting palm provides secure attachment to compatible bolted electrical connections, while the right-angle configuration allows the conductor to approach the mounting point from a different direction. This can help reduce excessive cable bending and improve the organisation of large power cables within electrical enclosures.
Designed for 150 mm² copper cables and an M12 mounting stud, the COL150-12/RA offers a practical termination solution for industrial switchgear, power distribution assemblies, motor control equipment and large-conductor electrical installations. Supplied in a convenient pack of 10 terminals, it is suitable for electrical contractors, panel builders, OEM manufacturers and industrial maintenance engineers.

Reliable Right-Angle Cable Terminations for Heavy-Duty Power Distribution
Right-angle copper tube terminals such as the Partex COL150-12/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 within electrical enclosures and power distribution assemblies.
The heavy-duty tubular barrel is designed to accept a correctly prepared 150 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 fastened to a compatible stud or bolted electrical connection point.
The 90° terminal configuration is particularly useful when large power cables must be routed around adjacent components, connected to busbars or terminated within restricted switchgear compartments. Because 150 mm² conductors can require substantial installation space and appropriate bending clearance, the angled design can help provide a more practical connection arrangement without forcing the cable into an unnecessarily tight bend.
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 COL150-12/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 fixing must also be verified for the intended application.
