Why Choose the Cembre RP-M4 2046020 Ring Terminal?
The Cembre RP-M4 2046020 is a professional pre-insulated ring terminal designed for reliable crimp termination of copper conductors in electrical panels, machinery, control systems and general electrical installations. Part of Cembre's P range of halogen-free insulated terminals, it combines an electrolytic copper terminal body with durable red polycarbonate insulation.
Designed for conductors from 0.25–1.5 mm², the RP-M4 provides a secure permanent connection to M4 studs and screws. Its ring has a 4.3 mm hole diameter, while the terminal's easy-entry design assists conductor insertion before crimping and helps make repetitive wiring work faster and more consistent.
The RP-M4 has an overall length of 20.1 mm and ring width of 7 mm. Its red insulation provides immediate identification of the conductor-size range, while the halogen-free construction makes the terminal suitable for demanding industrial and infrastructure applications where dependable electrical termination and material performance are important.

Reliable Crimp Termination for Electrical Installations
Ring terminals provide a mechanically secure electrical connection because the closed ring is retained around the fixing stud even if the fastening screw becomes partially loosened. When the RP-M4 is correctly crimped using a suitable tool, the conductor and terminal form a dependable connection suitable for control panels, equipment wiring and industrial electrical assemblies.
Cembre's RP-M range combines conductive copper terminal bodies with halogen-free polycarbonate insulation and easy-entry conductor insertion. The defined conductor and stud sizes make the RP-M4 particularly useful for repeatable production wiring where consistent termination quality and straightforward component identification are required.
