2046316 Cembre BP-M3.5/1 RING TERMINAL

Why Choose the Cembre 2046316 BP-M3.5/1 Insulated Ring Terminal?

The Cembre 2046316, also identified as BP-M3.5/1, is a professional pre-insulated ring terminal designed for secure termination of copper conductors in electrical panels, machinery, control systems and industrial installations. Part of Cembre’s P range of pre-insulated terminals, it combines a crimp connection with a closed ring design to provide a dependable electrical and mechanical connection to compatible studs and terminal points.

Designed for conductors from 1.5–2.5 mm², equivalent to 16–14 AWG, the 2046316 features blue halogen-free polycarbonate insulation and a high-purity electrolytic copper terminal body with tin plating. Its easy-entry construction helps guide conductor strands correctly into the barrel, supporting efficient and consistent crimp termination.

With an M3.5 stud size, the Cembre BP-M3.5/1 is particularly suitable for control panels, switchgear, machinery and other equipment requiring dependable termination of medium-size copper conductors. The closed ring configuration provides secure retention beneath the fixing screw or nut for reliable electrical connections in demanding applications.

Reliable Electrical Termination for Copper Conductors

Pre-insulated ring terminals provide a practical and secure method of terminating copper conductors onto threaded studs and screw connections. Once correctly crimped, the terminal creates a firm mechanical and electrical connection with the conductor, while the closed ring remains securely retained beneath the fixing screw or nut until the fastener is removed.

The Cembre BP range is designed for professional electrical installation and panel-building work. The BP-M3.5/1 combines high-purity tin-plated electrolytic copper with halogen-free polycarbonate insulation, easy conductor insertion and a broad operating temperature range, making it suitable for dependable wiring connections across industrial equipment and electrical control systems.
