Twin Insulated Bootlace Wire Crimp Ferrule End Terminal Lug-Green-4 sqmm

Specifications:

• Max voltage: 150°C UI=300V
• Material: Copper
• Insulating Material: PVC, Nylon
• Length of Pure Copper: 8mm
• Cable Size: 2 X 4sqmm
• Plating: Electro-plated tin

Safety Warnings:

• Crimper mismatch: Never use standard flat pliers to crush a ferrule. This creates an uneven, weak mechanical grip, increases electrical resistance, and leads to dangerous terminal overheating under load.
• Wire sizing: Do not use this 4sqmm ferrule with thicker or thinner wires. Mismatched sizing guarantees a loose connection or damaged strands.

Frequently Asked Questions

• Does this 4 mm² twin ferrule comfortably fit into standard 5 mm pitch screw terminal blocks?
  Not necessarily. A 4 mm² twin ferrule is designed for two 4 mm² wires, so its overall dimensions are larger than those of a 1.5 mm² ferrule. Compatibility with 5 mm or 5.08 mm pitch screw terminals depends on the terminal's wire-entry opening and clamping design. Always check the terminal manufacturer's specifications before use.
• Can this 4 mm² twin ferrule be reliably used in push-in spring-loaded connectors like WAGO lever connectors?
  Only if the specific connector supports ferrules of the required conductor size and dimensions. A 4 mm² twin ferrule may exceed the permitted wire-entry capacity of smaller connectors. Check the connector manufacturer's specifications for ferrule compatibility and maximum conductor size.
• What happens if I crush this 4 mm² twin ferrule with standard flat pliers instead of a proper crimping tool under a high-current load?
  Using flat pliers instead of a suitable ferrule crimping tool can produce an uneven or loose crimp. Under high current, this may increase contact resistance and cause overheating, terminal damage, insulation melting, or fire. Use a crimping tool designed for the specific ferrule size and profile, and follow the terminal manufacturer's instructions.
• Is the orange plastic insulation collar rated to safely handle mains voltage?
  The orange collar alone does not establish a voltage rating. Its colour may indicate the conductor-size range under a particular manufacturer's colour scheme, but colour conventions can vary. Mains-voltage suitability depends on the ferrule's insulation material, applicable certifications, and the complete terminal assembly's ratings.
• Should I twist the two 4 mm² stranded wires together before inserting them into the ferrule?
  No. Insert both stripped 4 mm² conductors straight and parallel into the twin ferrule without twisting them together. Ensure both conductors reach the end of the metal barrel and that no strands are left outside before crimping with a suitable tool.
• Does it matter which orientation the crimped 4 mm² twin ferrule is inserted into a standard screw terminal?
  The orientation is generally not important if the ferrule fits correctly and the terminal clamp makes proper contact. However, a 4 mm² twin ferrule may be too large for some terminal openings. Never force it into a terminal; verify the permitted conductor and ferrule dimensions first.
