This is our heavy duty 125A three phase extension lead for sites and temporary installs where you want dependable power and properly built kit. It suits workshops, site compounds, industrial maintenance, plant, temporary power setups, and anywhere you need a high capacity three phase feed with tough, reliable connectors.
Proper cable, built for real use
We build these using 35mm² 5 core H07RN F heavy duty rubber cable, selected for flexibility and toughness in demanding conditions. The cable meets the relevant harmonised standards, is UV resistant and flame retardant, and is a solid choice for professional use indoors or outdoors.
Why we offer 35mm² (and when to choose 50mm²)
This version uses 35mm², which is a great option when your load is typically up to around 102A.
If you need the full 125A capacity, we also offer a 50mm² version which is the right choice when you want maximum headroom.
Connectors: PCE 125A red
We fit genuine PCE connectors throughout:
-
PCE 045-6 plug: 125A, 3P + N + E, 400V class, 6h, red, IP66/67
-
PCE 245-6 connector: 125A, 3P + N + E, 400V class, 6h, red, IP66/67
Asset marking
Every cable is supplied with 12cm of clear heat shrink on both ends. It gives you a clean, durable area to add your asset ID, company name, barcodes, colour labels, or inspection tags without it peeling off or looking scruffy over time.
Built and checked properly
We build these like working kit, not box shifting leads:
- Bootlace ferrules used for tidy, reliable terminations
- Torque screwdrivers used so terminations are tightened to the correct specification
- Each cable is fully tested and PAT tested before it leaves us
Length options
Stock lengths: 2m, 5m, 10m, 20m, 30m, 50m.
Choose your length on the product page. We stock common lengths, and if you need something specific, check out our custom cable option so you can tell us the exact length and connectors you want and we’ll build it for you.
