Why Choose the Cembre 2046016 RP-M3.5/1 Ring Terminal?
The Cembre 2046016, manufacturer reference RP-M3.5/1, is a professional pre-insulated ring terminal designed for secure termination of copper conductors in electrical panels, machinery and industrial wiring systems. Its closed ring design provides a dependable mechanical connection to an M3.5 stud or screw and helps prevent accidental disconnection once the fixing has been tightened.
Designed for conductor cross-sections from 0.25–1.5 mm², the terminal features red polycarbonate insulation and a conductive body manufactured from high-purity electrolytic copper. The copper connector is tin plated to provide reliable electrical performance and additional surface protection in demanding electrical installations.
The RP-M3.5/1 is suitable for operating temperatures from -20–115 °C, with short-duration exposure up to 130 °C, while its polycarbonate insulation provides a UL 94 V-0 flammability rating. These characteristics make the terminal a practical choice for professional control-panel construction, machinery wiring, maintenance and general electrical termination work.

Secure Pre-Insulated Ring Termination for Electrical Wiring
Ring terminals provide a particularly secure method of terminating electrical conductors because the fixing screw or stud passes completely through the terminal. Unlike an open fork connection, the terminal cannot normally become detached without first loosening or removing the fixing, making ring terminals well suited to machinery and electrical installations where vibration or movement may be present.
The Cembre RP-M3.5/1 combines this secure connection method with a pre-insulated construction for efficient installation. The tin-plated copper body provides the conductive connection while the red polycarbonate sleeve insulates and supports the conductor termination. When installed using a suitable Cembre crimping tool, the terminal provides a consistent mechanical and electrical connection for professional wiring applications.
Typical Applications
- Industrial control-panel wiring.
- PLC and automation control systems.
- Machinery electrical wiring.
- Terminal blocks and stud connections.
- HVAC control and electrical systems.
- Lighting installations.
