Insulated ferrule Ergom HI 0.34 mm² / 8 mm turquoise, pack of 100

Insulated ferrule Ergom HI 0.34 mm² / 8 mm turquoise, pack of 100 is a set of end sleeves designed for crimping onto flexible and stranded conductors. Each ferrule has a nominal conductor cross-section of 0.34 mm² and an 8 mm insulated sleeve that eases insertion into terminal blocks and improves conductor-to-connection contact. Supplied in a pack of 100, these turquoise-coloured ferrules are suitable for electrical installations, control panels and other applications where secure, insulated terminations are required.

Advantages

These Ergom HI insulated ferrules offer consistent crimp quality and reduce the risk of stray strands and poor contact. The insulated sleeve provides electrical insulation and strain relief at the termination point while the metal tube ensures a reliable conductive connection. The uniform sleeve length and colour coding simplify identification during installation and maintenance.

Suitable for

• Crimp termination of flexible and stranded conductors with 0.34 mm² cross-section
• Wiring in control panels and terminal blocks
• Residential and light commercial electrical installations
• Maintenance and repair work requiring multiple identical insulated ferrules

Key specifications

• Nominal conductor cross-section: 0.34 mm²
• Sleeve (barrel) length: 8 mm
• Insulation: coloured insulated sleeve (turquoise)
• Material: conductive metal tube with insulating sleeve
• Pack quantity: 100 pieces

How to use

Strip the conductor to the correct length so that the bare wire fully enters the metal tube. Insert the conductor into the ferrule until the insulation meets the sleeve, then use a suitable crimping tool sized for 0.34 mm² ferrules to compress the metal tube evenly. After crimping, check that no wire strands protrude and that the ferrule is secure; then insert the ferrule into the terminal and tighten the connection according to the terminal manufacturer’s instructions.

Usage recommendations

Use a dedicated ferrule crimping tool matched to the 0.34 mm² size to achieve reliable, repeatable crimps. Keep ferrules in their pack until use to avoid contamination and sort by colour for quick identification during wiring tasks.
