Prolech large wire connector 4–6 mm² yellow pack 100 pcs (43-406#)

Prolech large wire connector for electrical wires is designed to connect and insulate single- and multi-core copper conductors with cross-sections from 4 to 6 mm². Supplied as a pack of 100 yellow quick connectors, this product is intended for building wiring, distribution boards and repair work where a reliable mechanical and electrical contact for medium‑gauge cables is required. The compact body and internal contact geometry enable fast installation without special tools for typical applications.

Advantages

The connector provides consistent electrical contact and mechanical retention for conductors in the 4–6 mm² range, reducing installation time compared with screw-type terminals. Its insulation body offers protection against accidental contact and short circuits during operation and handling. The uniform dimensions and colour coding simplify identification and stock management for electricians and installers.

Suitable for

• Connecting 4–6 mm² single- and multi-core copper conductors
• Building wiring and branch connections in residential and commercial installations
• Distribution boards and terminal blocks where compact connection is required
• Maintenance and repair tasks requiring quick, repeatable connections

Key specifications

• Conductor cross-section: 4–6 mm²
• Conductor type: single-core and multi-core copper
• Quantity in pack: 100 pieces
• Housing colour: yellow
• Connection type: quick push-in connector with internal contact
• Intended use: insulation and mechanical/electrical connection of medium‑gauge wires

How to use

Strip the conductor insulation to the recommended length for the connector, align the bare conductor with the connector entry and push it into the contact until it seats firmly. For multi-core conductors ensure all strands enter the contact without splaying. To remove, follow safe de-energised procedures and withdraw the conductor using appropriate tools if required. Do not use the connector with damaged conductors or with conductor sizes outside the specified range.

Usage recommendations

Use these connectors on installations that are de-energised and comply with local electrical regulations. Verify conductor cross-section and ensure wires are free of corrosion or insulation damage before connecting. For permanent or high-current installations, confirm compatibility with the circuit requirements and local standards.
