Full Overview of Niglon Protego Surge Protected Consumer Units
The Niglon Protego SPD consumer unit range offers electricians a reliable, regulation-compliant way to provide Type 2 surge protection straight from the distribution point.

Surge Protected Consumer Unit Buying Guide
When buying a surge protected consumer unit, there are a few key considerations:
- Number of usable ways: Match your current circuits and allow for future expansion.
- Build quality: Look for powder-coated steel, solid hinges, and a durable lid — all standard on the Protego range.
- SPD configuration: The Niglon Type 2 SPD mounts directly to the busbar, removing the need for a separate MCB and saving valuable space.
- Compliance: All models meet BS 7671:2018, BS EN 61439-3, and EN60947-3 standards.
Synonym Note: If you’re wondering how to choose a Type 2 SPD consumer unit, focus on both your current load needs and your potential future expansion.
Niglon Protego Main Switch Consumer Units Explained
The Niglon Protego main switch consumer units in this range use a twin screw 100A isolator on the incomer. This ensures solid cable retention and compliance with UK wiring regulations. The SPD fits directly to the busbar, creating a neat, space-saving layout.
Models range from:
- 1-Way (ideal for EV chargers or dedicated appliances)
- 3-Way and 7-Way (compact domestic boards)
- 11-Way and 15-Way (full-home rewires)
- 19-Way, 23-Way, and 31-Way (larger installations or small commercial)
Synonym Note: Often referred to as Protego range consumer units with main switch, these boards are built for both performance and ease of installation.
