£0.16
The Cembre 2054010 (GF-M3) is a premium pre-insulated ring terminal designed to provide secure, low-resistance electrical connections for industrial control panels, switchgear, machinery and OEM electrical installations. Manufactured by Cembre, this GF-Series terminal combines high-conductivity electrolytic copper with durable PVC insulation to deliver dependable long-term performance.
Manufactured from 99.95% pure annealed electrolytic copper with a corrosion-resistant tin-plated finish, the GF-M3 offers excellent electrical conductivity together with outstanding resistance to oxidation and harsh industrial environments. The internally knurled barrel improves conductor retention, while the funnel-entry insulated sleeve simplifies conductor insertion and helps protect conductor strands during crimping.
Designed for 4–6 mm² copper conductors with an M3 fixing hole, the GF-M3 provides a permanent and vibration-resistant connection, making it ideal for industrial control equipment, electrical panels, switchgear and maintenance applications.
Ring terminals provide one of the most secure methods of terminating stranded conductors onto threaded studs. Their closed-ring design offers excellent resistance to vibration, making them ideal for permanent electrical installations where long-term reliability is essential.
The Cembre GF-Series is manufactured using premium electrolytic copper with a corrosion-resistant tin-plated finish, internally knurled conductor barrel and colour-coded PVC insulation to provide dependable performance across demanding industrial applications.
