Cembre 2054890 GF-U12 yellow pre-insulated fork terminal for 4–6 mm² copper conductors and M12 fixing studs.
£0.49
The Cembre 2054890, also identified as the GF-U12, is a durable pre-insulated fork terminal designed to provide secure and dependable electrical connections for copper conductors. Manufactured as part of the established Cembre F series, this terminal is suitable for industrial control panels, electrical equipment and general wiring applications where reliable conductor termination is essential.
The GF-U12 combines a tin-plated copper terminal body with a yellow insulating sleeve, helping deliver good electrical conductivity, corrosion resistance and mechanical protection. Its fork-shaped connection allows the terminal to be installed or removed from a threaded stud without completely removing the fixing screw, making installation and maintenance more efficient.
Designed for 4–6 mm² copper conductors and an M12 stud or screw, the Cembre 2054890 is suitable for securely terminating larger control and power conductors. The yellow insulation provides quick conductor-size identification, while the straight terminal design supports neat and organised wiring installations.
Fork terminals provide an efficient method of connecting stranded copper conductors to terminal studs, equipment terminals and electrical components. Their open-ended design allows the terminal to slide beneath a partially loosened screw, reducing installation time while maintaining a secure mechanical and electrical connection.
The Cembre GF-U12 is designed for professional crimping applications where consistent electrical performance is required. When installed using a correctly sized Cembre-compatible crimping tool, the terminal creates a strong connection that helps resist conductor pull-out, vibration and movement within industrial electrical systems.
