Cembre 2160730 S1.5-U4/1 pre-insulated fork terminal for approximately 0.25 to 1.5 mm² copper conductors and M4 screw connections.
£0.16
The Cembre 2160730, also identified as the S1.5-U4/1, is a high-quality pre-insulated fork terminal designed for secure and efficient termination of stranded copper conductors. Manufactured by Cembre, this terminal provides a dependable electrical connection for control panels, machinery, switchgear and general industrial wiring applications.
Its open fork design allows the terminal to be installed or removed without completely taking the fixing screw out of the terminal block or equipment connection point. This helps reduce installation time while maintaining a reliable mechanical and electrical connection. The insulated sleeve supports safer handling and provides additional protection around the conductor entry point.
Suitable for copper conductors with a cross-sectional area of approximately 0.25–1.5 mm², the Cembre 2160730 is designed for use with M4 studs and screws. Its compact design makes it ideal for professional wiring tasks where space, consistency and connection reliability are important.
Fork terminals provide a practical method of connecting electrical conductors to screw terminals. Unlike closed ring terminals, the open fork profile can slide beneath a loosened screw head, allowing wiring to be installed or serviced without fully removing the screw.
The Cembre 2160730 is manufactured for consistent crimping performance when installed with a suitable crimping tool. A correctly formed crimp helps create a low-resistance electrical connection while reducing the risk of conductor strands loosening under vibration or repeated equipment operation.

The Cembre 2160730 is used to terminate stranded copper conductors onto screw terminals in control panels, machinery and electrical equipment.
The corresponding Cembre model reference is S1.5-U4/1.
This terminal is designed for copper conductors with a cross-sectional area of approximately 0.25–1.5 mm².
The fork connection is designed for use with approximately M4 studs or terminal screws.
The conductor is stripped, inserted into the insulated barrel and secured using a compatible crimping tool. The fork can then be positioned beneath a loosened terminal screw and tightened securely.
Cembre terminals are widely used by panel builders, electrical engineers and industrial maintenance professionals for dependable conductor termination and consistent connection quality.
