RS43/RA Partex Spade Terminals (Forks), M4, Red, pack 100

Why Choose the Partex RS43/RA Red Insulated Spade Terminal?

The Partex RS43/RA is a professional red insulated spade (fork) crimp terminal designed for connecting electrical conductors to compatible M4 screw terminals. Its open-ended fork configuration provides a convenient method of creating secure, screw-fixed electrical connections in control panels, industrial machinery, electrical equipment and wiring assemblies.

Unlike closed-ring terminals, the RS43/RA features a fork-shaped connection that can be positioned beneath a suitable screw head or clamping plate without completely removing the fixing, where the equipment design permits. This makes it particularly useful for electrical installations requiring convenient assembly, servicing or replacement of conductor connections.

The terminal features red insulation around the crimp barrel, helping protect the conductor termination area and providing convenient visual identification during installation. Its crimp-style construction enables a solder-free connection when used with a correctly sized conductor and an appropriate insulated-terminal crimping tool.

Supplied in a practical pack of 100 terminals, the Partex RS43/RA is suitable for electricians, control panel builders, equipment manufacturers and maintenance engineers who require reliable, repeatable electrical connections.

Convenient M4 Fork Connections for Electrical Installations

Spade terminals are widely used in electrical wiring because they provide a convenient method of attaching a conductor to a screw-fixed connection point. The Partex RS43/RA features an open-ended fork designed to fit around a compatible M4 screw or stud. This allows the connection to be assembled or removed without necessarily extracting the screw completely, helping simplify maintenance and wiring modifications.

The terminal's red insulated crimp barrel covers the conductor termination area and assists with identification. When installed using a correctly matched crimping tool, the terminal provides a mechanical and electrical connection between the conductor and the fork contact. Correct crimping is essential for maintaining conductor retention and consistent electrical performance.

To install the RS43/RA, the conductor should be stripped to the appropriate length without damaging its strands. The prepared conductor is then inserted fully into the crimp barrel and secured using a suitable insulated-terminal crimping tool. The fork is positioned beneath the compatible M4 fixing and tightened in accordance with the equipment manufacturer's instructions.

Before installation, users should confirm that the conductor cross-sectional area, insulation diameter, fork dimensions and electrical ratings are suitable for the intended application. Red insulation is commonly associated with smaller conductor sizes, but the correct conductor range should always be verified against the specific product's technical data rather than determined from colour alone.

Typical Applications

• Electrical control panel assembly and terminal wiring.
• Connections to compatible M4 screw terminals and studs.
• Industrial machinery and automation equipment wiring.
• Electrical equipment manufacturing and cable harness assembly.
• Maintenance and replacement of insulated spade terminal connections.
• General electrical installations requiring accessible screw-fixed conductor terminations.
