Why Choose the Cembre 2050110 RF-M3.5/1 Insulated Ring Terminal?
The Cembre 2050110, also identified as RF-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. Its closed ring design provides a dependable electrical and mechanical connection to compatible M3.5 studs and screw terminals.
Designed for conductors from 0.25–1.5 mm², the 2050110 features red PVC insulation and a terminal body manufactured from high-purity electrolytic copper. The insulated crimp barrel helps protect the conductor termination while the easy-insertion design supports efficient and consistent installation.
With an M3.5 stud size and approximately 3.7 mm ring opening, the Cembre RF-M3.5/1 is particularly suitable for control panels, industrial machinery, HVAC equipment and other electrical systems requiring dependable small-conductor termination. The closed ring remains securely retained beneath the fixing screw or nut until the fastener is removed.
