Why Choose the Partex PXL400-20 Copper Tube Ring Terminal?
The Partex PXL400-20 is a copper tube ring terminal designed for terminating 400 mm² electrical conductors onto compatible M20 stud connections. Supplied in a pack of 10 terminals, this large-conductor crimp cable lug provides a practical termination solution for industrial electrical installations, power distribution equipment and heavy-duty electrical assembly applications.
As part of the Partex PXL copper tube terminal range, the PXL400-20 combines a tubular conductor barrel with a ring-shaped mounting palm. The barrel receives a suitably prepared electrical conductor and is compressed using compatible crimping equipment, while the ring palm allows the terminated cable to be secured to an M20 stud or suitable bolted electrical connection.
With its 400 mm² nominal conductor size, M20 stud fixing and 10-piece pack quantity, the PXL400-20 is suited to larger-conductor termination work in electrical distribution assemblies, industrial machinery and power connection systems. Correct conductor preparation, crimping and connection tightening are essential for achieving a dependable electrical and mechanical termination.

Heavy-Duty Copper Crimp Connections for Large Power Conductors
The Partex PXL400-20 copper tube ring terminal provides a connection between a compatible 400 mm² electrical conductor and an M20 bolted terminal point. During installation, the conductor is stripped to the appropriate length, inserted into the tubular barrel and compressed using correctly selected crimping equipment. A properly formed crimp establishes the mechanical and electrical connection between the conductor and terminal.
For large-section conductors, correct installation is particularly important. The installer should verify conductor material and construction, terminal barrel compatibility, the specified crimping die and the required crimping procedure. The ring-shaped palm is then secured to the M20 connection point using the equipment manufacturer's recommended fixing arrangement and tightening torque. Proper crimp formation, clean contact surfaces and secure bolted fastening help maintain a dependable electrical connection.
Typical Applications
- Industrial electrical power distribution assemblies.
- Low-voltage switchgear and distribution equipment.
- Main electrical distribution boards and power panels.
- Industrial machinery power cable terminations.
- Large motor and industrial drive power connections.
- Electrical equipment with compatible M20 terminal studs.
- Power supply and electrical distribution connections.
- Industrial electrical maintenance and cable replacement work.
- OEM electrical equipment manufacturing and assembly.

Frequently Asked Questions
What is the Partex PXL400-20 used for?
The Partex PXL400-20 is a copper tube ring terminal used to connect a compatible 400 mm² electrical conductor to an M20 stud or bolted terminal using a crimped cable termination.
What cable size is suitable for the Partex PXL400-20?
The PXL400-20 is designed for a nominal conductor cross-section of 400 mm². The conductor material, construction and dimensions must also be checked for compatibility before crimping.
What stud size does the PXL400-20 fit?
The PXL400-20 features a ring connection intended for an M20 stud. The mating stud, contact surface and fixing arrangement must be suitable for the electrical connection.
What material is the Partex PXL400-20 made from?
The PXL400-20 is a copper tube ring terminal. Copper provides an electrically conductive connection between the terminated conductor and the bolted equipment connection point.
How is the Partex PXL400-20 installed?
The conductor is stripped to the appropriate length, inserted into the tubular barrel and crimped using a compatible heavy-duty tool and die. The ring palm is then secured to the M20 connection point using the electrical equipment manufacturer's recommended tightening procedure.
What crimping tool is required for the PXL400-20?
A crimping tool and die suitable for the 400 mm² conductor and the terminal's barrel construction are required. Heavy-duty hydraulic crimping equipment may be appropriate, subject to the terminal and tool manufacturers' instructions. The correct die, crimping profile and procedure must be confirmed before installation.
How many Partex PXL400-20 terminals are supplied in each pack?
Each pack contains 10 Partex PXL400-20 copper tube ring terminals, making the product suitable for industrial electrical installation projects, equipment assembly and maintenance inventories.
What is the difference between the PXL400-20 and PXL400-16?
Both terminals are designed for 400 mm² conductors, but they have different stud connection sizes. The PXL400-20 is intended for an M20 stud, whereas the PXL400-16 is intended for an M16 stud.
Can the Partex PXL400-20 be reused after crimping?
Crimped cable terminals are generally intended for permanent attachment to the conductor. If a terminal is damaged or must be removed from the cable, it should be replaced rather than attempting to reuse the compressed barrel.
What should be checked before installing the PXL400-20?
Confirm the 400 mm² conductor size, conductor material and construction, M20 stud compatibility, correct crimping equipment, suitable connection surfaces and the electrical equipment manufacturer's tightening requirements before installation.
