Why Choose the Cembre 2146020 GKY-U3.5 Reinforced Insulated Fork Terminal?
The Cembre 2146020 GKY-U3.5 is a premium yellow reinforced insulated fork (spade) terminal engineered to provide secure, vibration-resistant electrical terminations for industrial control panels, switchgear, machinery and OEM equipment. Manufactured by Cembre, this professional-grade fork terminal is designed for demanding applications where reliable electrical performance and mechanical durability are essential.
Manufactured from tin-plated electrolytic copper with a durable halogen-free PA6.6 insulated sleeve, the GKY-U3.5 delivers excellent electrical conductivity, corrosion resistance and long service life. Its reinforced anti-vibration copper sleeve becomes part of the crimp during installation, creating a highly secure electrical and mechanical connection even in environments subjected to continuous vibration and movement.
Designed for 4–6 mm² conductors and featuring a 3.7 mm fork opening, the Cembre 2146020 enables rapid installation and removal without completely removing the fixing screw, making it ideal for maintenance applications and professional electrical installations.
