Bootlace terminal insulated copper 4 mm² polyamide — EB1390624809

Insulated bootlace terminal for 4 mm² copper conductors with a polyamide sleeve designed for crimping. This bootlace terminal provides a protected, compact termination for stranded copper wires, improving contact reliability in terminal blocks, control panels and electrical equipment. The polyamide insulation covers the wire end to reduce risk of short circuits and to provide mechanical strain relief at the connection point.

Advantages

The polyamide insulating sleeve resists abrasion and offers consistent electrical insulation while remaining compact for tight installation spaces. Crimp-style attachment ensures a secure, low-resistance connection when processed with an appropriate crimping tool. The terminal's copper conductor element provides good conductivity and corrosion resistance when properly installed. Its consistent shape and dimensions simplify repeated terminations and support reliable mating with standard terminal blocks and screw connections.

Suitable for (tasks / use cases)

• Terminating stranded 4 mm² copper conductors before insertion into terminal blocks
• Making secure connections in control panels and distribution boards
• Electrical equipment manufacturing and field wiring where compact insulated ends are required
• Repair and maintenance work on machinery and PLC wiring

Key specifications

• Cable cross-section suitability: 4 mm² stranded copper conductors
• Contact material: copper conductive element
• Insulation material: polyamide sleeve providing electrical and mechanical protection
• Termination type: crimp bootlace (ferrule) style
• Typical application: terminal block insertion, screw terminal connections and panel wiring

How to use

Strip the conductor to the appropriate length so that the bare strands fully enter the copper barrel. Insert the stripped wire into the barrel until the insulation abuts the sleeve. Use a suitable ferrule or bootlace crimping tool to compress the copper barrel evenly, forming a gas-tight connection between conductor strands and terminal. After crimping, visually inspect the crimp for uniform compression and ensure the insulated sleeve covers the conductor insulation to prevent exposed strands. Insert the terminated end into the terminal block or screw connection and tighten the screw to the manufacturer’s recommended torque.

Usage recommendations

Use a crimping tool matched to bootlace terminals for consistent results; avoid pliers-style crimps. Select the correct strip length and ensure the crimped barrel is free of loose strands. For environments with higher vibration or corrosive conditions, verify compatibility with additional protective measures such as lacquer or protective sleeves.
