Cembre 2046040 RP-M8/PK red pre-insulated M8 ring terminal for 0.25 to 1.5 mm² stranded copper conductors, featuring halogen-free polycarbonate insulation and a tin-plated copper terminal body.
£0.19
The Cembre 2046040, also identified as the RP-M8/PK, is a professional-quality pre-insulated ring terminal designed to create secure electrical and mechanical connections on stranded copper conductors. Manufactured as part of the Cembre P range, this terminal is suitable for control panels, machinery, transportation systems and other installations where dependable cable termination is essential.
The terminal features a red, halogen-free polycarbonate insulation sleeve with a funnel-shaped conductor entry. This design helps guide conductor strands fully into the terminal barrel, reducing the risk of stray strands and supporting a consistent, reliable crimp. Its self-extinguishing insulation provides additional safety in demanding electrical environments.
Designed for conductor sizes from 0.25 to 1.5 mm², the Cembre 2046040 incorporates an M8 ring connection for attachment to threaded studs, bolts and terminal posts. The terminal body is manufactured from high-conductivity electrolytic copper and tin plated to improve corrosion resistance and long-term connection performance.
Ring terminals provide a secure cable connection by allowing the terminal palm to be fastened beneath a nut, screw or threaded stud. Unlike fork terminals, the closed ring cannot be removed without fully releasing the fixing, helping maintain connection integrity in installations exposed to movement, vibration or routine maintenance.
The Cembre 2046040 combines a high-conductivity copper terminal body with protective insulation and a flared conductor entry. When installed using a compatible crimping tool, it creates a durable connection suitable for industrial control wiring, equipment manufacturing and electrical distribution applications.
