Lapp L-RC 4 F Tubular Fork Lug, Copper Plated, Straight Connector

The Lapp L-RC 4 F is a professional-grade tubular fork lug engineered for secure and efficient electrical terminations. Designed with a straight connector configuration, this component facilitates reliable contact in various wiring applications. The lug features high-quality copper plating, which ensures excellent electrical conductivity and long-term performance. Each unit is built to withstand demanding environments, providing a stable connection that minimizes resistance and prevents common wiring failures.

Advantages

This tubular fork lug offers significant benefits for electrical assembly, primarily through its specialized Easy-Entry funnel design. This feature allows for the quick and safe insertion of conductors, effectively eliminating the risk of bent or crushed cable strands during installation. The construction includes a double-folded and hard-soldered flat receptacle, which enhances structural integrity and improves current conduction. Furthermore, the electrolytic tinning provides superior protection against corrosion, ensuring that the connection remains stable even in challenging conditions. The internal corrugation of the metal sleeves provides additional grip, while the hard-soldered design allows the lug to be pressed in any orientation without compromising the connection quality.

Suitable for

• Professional electrical installations
• Control cabinet wiring
• Industrial automation systems
• General maintenance and repair of electrical equipment
• Projects requiring secure fork-type terminations

This product is not suitable for high-voltage power transmission lines or applications involving extreme mechanical vibration that requires a bolted ring terminal for added security. It is also not intended for use with conductors that exceed the specified gauge range, as this would compromise the integrity of the crimp.

Key specifications

• Connector type: Straight tubular fork lug
• Material: Copper with electrolytic tinning
• Design: Easy-Entry funnel for conductor insertion
• Construction: Double-folded and hard-soldered receptacle
• Internal features: Metal sleeves with internal corrugation
• Quantity per pack: 100 pieces

To use the Lapp L-RC 4 F, first strip the insulation from the end of the conductor to the appropriate length. Insert the conductor into the Easy-Entry funnel until the strands are fully seated within the metal sleeve. Use a compatible crimping tool to apply pressure to the sleeve, ensuring a secure mechanical and electrical bond. The hard-soldered construction allows for crimping in any position, providing flexibility during installation in tight spaces.

What to consider before purchase

• Ensure the conductor gauge matches the lug specifications
• Verify the terminal screw size (M4) for compatibility
• Confirm the crimping tool is suitable for insulated fork lugs
• Assess the environmental conditions to ensure tinning provides sufficient protection

For optimal performance, always use a calibrated crimping tool designed for insulated terminals. Ensure that the conductor is clean and free of oxidation before insertion to maintain maximum conductivity.
