3-Phase to Single Phase 16A 5-Pin Red Plug to 16A 230v Coupler

HDIUK 3-Phase to Single-Phase 16 A Converter Lead | 400 V 5-Pin Plug to 230 V 16 A Coupler
Power standard 230 V tools and appliances directly from a 400 V three-phase socket — no rewiring needed. Many warehouses and venues only have 5-pin (3P + N + E) outlets. Instead of replacing them, use this cost-effective converter to safely supply single-phase 230 V equipment from existing three-phase infrastructure and save thousands in installation costs.

Reliable Conversion for 230 V Equipment

Built in the UK using 1.5 mm² Arctic-grade PVC flex (BS 6004 Arctic Blue), the HDIUK 3-Phase to Single-Phase 16 A Converter Lead takes power from one phase (L1), Neutral (N) and Earth (E) of a 400 V supply to create a standard UK single-phase output. It connects a red 5-pin 16 A CEE plug to a blue 3-pin 16 A CEE coupler and delivers up to ≈ 3.6 kW for tools, lighting and catering equipment.

Key Features

• Input: 400 V 16 A CEE Red 5-Pin Plug (3P + N + E)
• Output: 230 V 16 A CEE Blue Coupler (2P + E)
• Cable: 1.5 mm² Arctic Blue PVC flex — cold-rated, high-visibility and lightweight
• Capacity: 16 A @ 230 V (≈ 3.6 kW)
• Compliance: Built to IEC 60309 and BS EN 60309-2 standards
• Tested & Certified: Individually PAT-tested and assembled in Hampshire by HDIUK Ltd

How It Works (Plain English)

The HDIUK 3-Phase to Single-Phase 16 A Converter Lead uses one phase of a three-phase circuit — L1 plus Neutral and Earth — to give you 230 V just like a domestic socket. The other two phases (L2 and L3) are safely terminated. In short: keep your 5-pin sockets and use this adapter instead of installing new 230 V outlets.

Choosing Between 16 A and 32 A Versions

Both versions work the same way but handle different currents and use different-size connectors. To know which you need, check the rating on the flap of your socket — it will state “16 A” or “32 A”.

• 16 A version: smaller connector, 1.5 mm² Arctic Blue cable, ≈ 3.6 kW load
• 32 A version: larger connector, 4 mm² Arctic or Titanex cable, ≈ 7.3 kW load — see our HDIUK 3-Phase to Single-Phase 32 A Converter Lead

Tip: If your socket is 32 A but your appliance has a 16 A plug, use our HDIUK 32 A Plug to 16 A Coupler (230 V) Converter Cable to connect safely without rewiring.

Typical Applications

• Workshops and warehouses with only 3-phase sockets
• Event and festival power distribution
• Catering and lighting systems
• Maintenance and generator setups
