## Summary description

Erko tin-plated crimp ferrules TA for insulated cable ends, size 4 mm² cross-section and 12 mm length. Supplied in a pack of 100 pieces, these ferrules provide reliable conductor termination, improve connection consistency and prevent strand fraying in screw or terminal block connections. Suitable for control panels, distribution boards and general electrical installations.

## Long description

Erko tin-plated crimp ferrules TA 4 mm² x 12 mm are designed for terminating stranded copper conductors in screw terminals and terminal blocks. Each ferrule measures 12 mm in length and accommodates a 4 mm² conductor cross-section. Supplied in a pack of 100 pieces, these ferrules provide a consistent, compact sleeve over the conductor strands to prevent fraying and ensure reliable electrical and mechanical contact in control panels, distribution boards and various electrical installations.
Advantages
These tin-plated crimp ferrules offer corrosion resistance from the tin finish and uniform conductor compression when crimped, resulting in stable low-resistance connections. The consistent inner bore and flared entry speed up wire insertion and reduce the risk of stray strands. Bulk packaging of 100 pieces supports efficient on-site use and reduces handling time during repetitive termination tasks.
Suitable for
Terminating stranded copper conductors of 4 mm² in screw-type terminals
Control panels and distribution board wiring
Field electrical installations and maintenance work
Terminal block connections in industrial equipment
Key specifications
Conductor cross-section: 4 mm²
Barrel length: 12 mm
Finish: tin-plated
Material: metal sleeve suitable for crimping on stranded copper
Pack quantity: 100 pieces
How to use
Prepare the stranded conductor by cutting to length and stripping insulation to expose the required conductor length. Insert the stripped conductor fully into the ferrule barrel until the insulation butts against the ferrule entry. Use an appropriate crimping tool sized for 4 mm² ferrules and perform a single, firm crimp on the barrel to compress the sleeve onto the conductor. After crimping, check that the ferrule is secure and that no strands protrude. Insert the ferrule-terminated conductor into the terminal and tighten the screw or clamp to the manufacturer’s recommended torque.
Usage recommendations
Use a calibrated crimping tool designed for ferrules of the specified cross-section to achieve a reliable, low-resistance connection. Match ferrule length and conductor strip length so the insulation does not enter the clamped area, and avoid re-crimping on the same ferrule to maintain mechanical integrity.
