Why Choose the Cembre 2054030 GF-M3.5 Ring Terminal?
The Cembre 2054030 GF-M3.5 is a premium yellow pre-insulated ring terminal designed to provide secure, permanent electrical terminations for stranded copper conductors. Part of the professional Cembre GF-M series, it is ideal for industrial control panels, switchgear, OEM equipment, power distribution systems and commercial electrical installations.
Manufactured from over 99.95% pure electrolytic copper with a high-quality tin-plated finish, the GF-M3.5 delivers outstanding electrical conductivity together with excellent resistance to corrosion and oxidation. The knurled internal barrel improves conductor grip during crimping, while the funnel-shaped insulated entry simplifies conductor insertion and helps prevent strand damage.
Designed for 4–6 mm² copper conductors, the GF-M3.5 features a M3.5 ring connection that provides a secure fixing where complete retention beneath the terminal screw is required. Cembre part number 2054030 is supplied in packs of 100 terminals.
