When you need a clean, gas-tight connection for multi-stranded copper wire, insulated cord end terminals (also called wire ferrules or bootlace ferrules) are the first component every electrician reaches for. They prevent stray strands, reduce contact resistance, and keep panels looking professional — all in one simple crimp.
What Are Insulated Cord End Terminals?
Insulated cord end terminals are small metal tubes with a color-coded insulating collar. The tube is crimped onto the stripped end of a wire, turning fragile strands into a solid “pin” that can be safely inserted into terminal blocks, circuit breakers, contactors, and distribution blocks.
Our range covers the most common industrial wire sizes and terminal types used in control cabinets, switchgear, automation systems, and building wiring:
- Insulated cord end terminals (single and twin-entry)
- Non-insulated ring terminals for bolt-on connections
- Fork / spade terminals for screw clamp applications
- Pin terminals for narrow terminal blocks
- Copper cable lugs for heavy-current terminations
Size Chart & Color Coding
All cord end terminals are marked by cable cross-section and barrel length. The insulation color follows the German/French standard, so one glance tells you which wire size each ferrule fits. We supply sizes from 0.14 mm² up to 50 mm², covering A.W.G. ranges from #28 to 250/300 kcmil.

Where Are They Used?
Because the crimp creates a gas-tight seal, cord end terminals are ideal anywhere vibration, oxidation, or repeated maintenance could loosen a wire:
- PLC and relay terminal blocks
- Power distribution rails and busbars
- Switchgear and motor control centers
- Solar inverters and battery systems
- Building automation and HVAC control panels
