32A 4-Pin Three Phase Extension Lead 400V

32A 4-Pin Three Phase Extension Lead 400V is a premium British-made extension lead designed for high-power applications. Built with ultra-tough Titanex H07RN-F 4G4 (4 mm²) cable, this lead ensures dependable industrial power for welders, generators, plant tools, and workshop machinery.

What This Is For

This extension lead is used to extend high-power three-phase connections for balanced loads up to 32 Amps. Its 4-pin layout (3 live phases + earth) is ideal for applications where no neutral is required, making it perfect for motors, welders, and plant equipment.

Key Features

• Cable: Titanex H07RN-F 4G4 rubber cable – 4 × 4 mm² cores
• Durability: Oil-, UV- and flame-resistant (−25 °C to +90 °C)
• Compliance: BS EN 50525-2-21 / CE marked
• Built in the UK by MotorCables – each lead individually tested

Technical Specs

• Length Options: 5 m, 10 m, 15 m, 20 m, and 25 m (custom lengths available upon request)
• IP Rating: IP44
• Cable Type: Titanex H07RN-F 4G4

Compatibility & Safety Notes

Ensure that your plug and socket types match before use. If your supply uses a 5-pin outlet, you can adapt it using a 32 A 5-Pin → 4-Pin Conversion Cable. For outdoor or custom breaker setups, consider using an IP65 Mini Inline Breaker Box. Always use genuine Titanex Cable Coils for safe extensions and consistent load capacity.

Frequently Asked Questions

Can I use this 32 A 4-Pin lead with a three-phase welder?

Yes – it’s ideal for three-phase welders that don’t require a neutral. Check your welder uses a 4-pin plug type or adapt with our 5-Pin → 4-Pin converter.

What’s the difference between 4-Pin and 5-Pin three-phase leads?

A four-pin lead carries three phases and earth; a five-pin lead also carries neutral. A correctly wired five-pin to four-pin adapter can omit neutral for equipment that does not need it. An adapter cannot create a missing neutral from a four-pin supply.

Is this Titanex extension lead suitable for outdoor use?

Yes – the IP44 connectors and rubber H07RN-F sheath are rain-resistant and safe for construction and event power applications.

Can I run this lead from a generator on site?

Absolutely – this lead is commonly used with generators featuring 32 A 4-Pin outlets on industrial and event sites.

How long can I run a 32 A 4 mm² extension before voltage drop?

All cable lengths have voltage drop. Assess the required length against the load, supply conditions and equipment requirements rather than treating 30 m as universally safe.

What should I check before choosing a four-pin extension lead?

This four-pin lead is for equipment requiring three phases and earth without neutral. Ask MotorCables if you need help matching the connector, current rating and cable length.
