## Summary description

Copper lug HiSmart NV822041 designed for use with 4 mm² electrical cable. Supplied as a pack of 10, these crimp/connect lugs provide a reliable conductive connection for wiring, terminal blocks and busbars in electrical installations. Suitable for general electrical, automotive and industrial applications where a durable copper terminal is required.

## Long description

Copper lug HiSmart NV822041 for 4 mm² cable, supplied in a pack of 10, is a crimp/connect terminal made of high-purity electrolytic copper with an electro-tin plated surface. It is designed for low-voltage electrical connections where a reliable conductive link between a 4.0 mm² conductor and a bolt, terminal block or busbar is required. Each lug includes a stud hole and an inspection hole to verify correct conductor insertion; lugs are fully annealed to ensure good ductility and ease of crimping.
Advantages
Manufactured from ≥99.9% electrolytic copper for high conductivity, with electro-tin plating to improve corrosion resistance and solderability. The built-in stud hole fits 6 mm bolts and the inspection hole allows quick visual verification of correct cable placement. Fully annealed construction provides optimal flexibility for secure crimping and long-term mechanical reliability.
Suitable for
Low-voltage electrical installations
Automotive wiring and battery connections
Industrial control panels and terminal blocks
Busbar and chassis connections

Crimp the barrel with a suitable crimping tool for 4.0 mm² lugs or solder if required. Ensure the stud or bolt is tightened to the equipment manufacturer's recommended torque for the bolt size to secure the connection.
Usage recommendations
Use a correct-size crimping die rated for 4.0 mm² copper lugs and verify conductor insertion through the inspection hole before crimping; apply anti-corrosion compound on exposed connections if used in corrosive environments.
