£0.16
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.
Ring terminals provide the most secure method of terminating stranded conductors onto threaded studs and screw terminals. The closed-ring design prevents accidental disconnection caused by vibration or maintenance, making them ideal for critical electrical connections in industrial environments.
The Cembre GF-M3.5 combines premium electrolytic copper construction, precision manufacturing and high-quality insulation to deliver long-term electrical reliability and mechanical strength.
