• A metal tube (typically made of copper or tin-plated copper) that is crimped onto the end of a stranded wire.

• Surrounded by a colored insulating collar made from plastic (usually nylon or PVC), which provides strain relief and electrical insulation.

• Improves electrical contact: Prevents stray wire strands from spreading, ensuring a solid, reliable connection.

• Reduces wear: Protects the wire from damage due to vibration or repeated insertion/removal.

• Prevents short circuits: The insulation keeps wires from contacting adjacent terminals or components.

• Simplifies wiring: Makes it easier to insert into terminals and improves the quality of the crimp connection.

• Control panels

• Switchboards

• Industrial machinery

• HVAC systems

• Anywhere stranded wire is used in screw terminals

Colors often indicate the wire size (though the exact colors can vary by region or manufacturer):

(Always check manufacturer specifications for exact color-code systems.)

1. Strip the insulation from the wire (usually about 10–12 mm).

2. Insert the stripped wire into the ferrule.

3. Use a crimping tool specifically designed for insulated ferrules.

4. Insert the crimped end into your terminal block or device.
