COL400-16 Partex copper tube ring terminal, 400mm², M16 stud, pack 5

Why Choose the Partex COL400-16 Copper Tube Ring Terminal?

The Partex COL400-16 is a heavy-duty copper tube ring terminal designed for the secure electrical termination of 400 mm² copper conductors. Featuring an M16 stud fixing, this industrial crimp cable lug provides a practical solution for connecting large-section copper power cables to compatible electrical equipment, busbars and bolted terminals.

Part of the Partex COL copper tube terminal range, the COL400-16 combines a robust tubular crimp barrel with a flat ring-type fixing palm. Its copper construction supports efficient electrical current transfer, while the straight terminal configuration provides a direct connection between the cable and equipment fixing point. When installed using correctly matched crimping equipment, the terminal creates a secure mechanical and electrical connection suitable for demanding industrial applications.

Designed for 400 mm² copper cables and M16 bolted connections, the COL400-16 is suitable for heavy-duty power distribution, industrial switchgear, electrical distribution cabinets and large electrical equipment assemblies. Its substantial conductor capacity makes it particularly useful in installations requiring large copper power cables. Supplied in a pack of 5 terminals, it provides a convenient quantity for specialist electrical contractors, panel builders, industrial maintenance engineers and OEM equipment manufacturers.

Reliable Heavy-Duty Cable Termination for Industrial Power Systems

Copper tube ring terminals provide a practical method of connecting large copper conductors to electrical equipment. The Partex COL400-16 incorporates a tubular crimp barrel designed for a 400 mm² copper conductor and a flat fixing palm with an M16 stud hole. This arrangement allows substantial power cables to be securely terminated onto compatible busbars, equipment studs and electrical connection points.

The terminal's copper construction provides an effective conductive path when correctly crimped and installed. Its straight ring terminal design is particularly useful in industrial power distribution boards, switchgear assemblies, motor control centres and electrical cabinets where robust bolted cable connections are required. The tubular barrel supports a secure conductor connection, while the ring palm provides a stable mechanical interface with the connected equipment.

For dependable electrical performance, the COL400-16 should be installed using a crimping tool and die specifically suitable for the 400 mm² terminal and conductor combination. The conductor must be correctly prepared and fully inserted into the barrel before crimping. The M16 fixing should then be secured using appropriate hardware and the tightening torque specified by the connected equipment manufacturer. Suitable insulation, electrical clearances and cable support must also be provided. The permissible operating current depends on the complete cable and connection assembly rather than the terminal size alone.

Typical Applications

• Heavy-duty industrial power distribution systems.
• Industrial switchgear and electrical distribution assemblies.
• Large electrical distribution boards and cabinets.
• Busbar connections with compatible M16 fixing points.
• Motor control centres and industrial motor power connections.
• Industrial machinery and manufacturing equipment.
• Electrical panel manufacturing and OEM equipment assembly.
• Large-section copper power cable termination.
• Industrial electrical maintenance and equipment refurbishment.
• Power distribution installations requiring 400 mm² copper conductors.
• Bolted cable connections to compatible M16 equipment terminals.
