Why Choose the Partex COL50-12/RA Right-Angle Copper Tube Terminal?
The Partex COL50-12/RA is a high-quality 90° right-angle copper tube terminal designed to provide secure, reliable electrical connections for 50 mm² copper conductors. Featuring an M12 stud connection and a robust tin-plated copper construction, this cable lug is ideal for industrial electrical installations, switchgear, control panels and power distribution equipment.
As part of the Partex COL copper tube terminal range, the COL50-12/RA is manufactured from high-conductivity copper and finished with bright electro-tin plating to improve corrosion resistance and maintain dependable electrical contact. Its right-angled palm design enables convenient cable termination where installation space is restricted or where a straight cable lug would create excessive cable bending.
Designed for 50 mm² cables and M12 bolted connections, this terminal incorporates a bell-mouth cable entry to simplify conductor insertion and an inspection hole to help verify correct cable positioning before crimping. Supplied in a pack of 50 terminals, the COL50-12/RA provides a practical solution for electrical contractors, panel builders and industrial maintenance engineers.

Reliable Electrical Connections in Confined Installations
Copper tube terminals are used to create secure electrical connections between stranded copper cables and equipment connection points. The Partex COL50-12/RA combines a crimpable tubular barrel with a 90° angled fixing palm, allowing the cable to approach the connection point at a right angle. This arrangement is particularly useful in electrical cabinets, switchboards and other installations where cable routing space is limited.
The terminal's high-conductivity copper body provides an effective electrical connection when correctly crimped, while the electro-tin-plated surface helps protect against oxidation and corrosion. The bell-mouth entry facilitates conductor insertion, and the inspection hole enables installers to check that the cable is correctly seated before applying the crimp.
For dependable performance, the COL50-12/RA should be installed using a crimping tool and die suitable for 50 mm² copper tube terminals. The M12 fixing should be secured using the appropriate fastening hardware and tightening torque specified for the connected equipment. Correct cable preparation, crimping and installation are essential for maintaining a reliable electrical connection.

Frequently Asked Questions
What is the Partex COL50-12/RA used for?
The Partex COL50-12/RA is a 90° right-angle copper tube terminal used to connect 50 mm² copper cables to electrical equipment with M12 bolted connection points. It is commonly used in electrical distribution panels, switchgear, industrial machinery and control cabinets.
What cable size is compatible with this terminal?
The COL50-12/RA is designed for 50 mm² copper conductors. Its tubular barrel is dimensioned to accommodate suitable standard electrical cables and must be crimped using compatible tooling.
What stud size does the COL50-12/RA fit?
This terminal is designed for an M12 stud or bolt connection, making it suitable for electrical equipment with compatible 12 mm nominal fixing points.
Why choose a right-angle copper tube terminal?
A 90° right-angle terminal allows the cable to approach the bolted connection from the side rather than directly in line with the fixing point. This helps simplify cable routing in confined spaces and can reduce the need for tight cable bends inside electrical enclosures.
What material is the terminal manufactured from?
The COL50-12/RA is manufactured from high-conductivity copper with a bright electro-tin-plated finish. This combination provides good electrical conductivity and improved resistance to surface corrosion.
Does this terminal require a crimping tool?
Yes. The terminal is designed for mechanical crimping onto a compatible 50 mm² copper conductor. A suitable cable lug crimping tool and correctly sized die should be used to achieve a secure connection.
How many terminals are included in a pack?
This product is supplied as a pack of 50 Partex COL50-12/RA right-angle copper tube terminals, suitable for electrical installation, panel assembly and maintenance applications.
