The 4 Way Metal Box with 40A MCB and Type 2 Surge Protection Device is a compact distribution solution ideal for EV charger supplies, outbuildings, and small sub-mains. Supplied built-to-order, it combines circuit protection and surge defence in a durable steel enclosure, saving space and install time on site.

To give you flexibility on site, this unit is available in multiple breaker variants. Whether you need a domestic option for standard loads or a device built to handle heavier inrush currents, you can choose the configuration that best suits your install:

  • 40A B Curve MCB + SPD – suited for standard domestic circuits
  • 40A C Curve MCB + SPD – designed for circuits with higher inrush currents such as motors or certain EV chargers
  • 32A B Curve MCB + SPD – for lower-rated installs where 32A protection is required

No matter which variant you select, every unit is built with the same robust enclosure and compliance standards to help you pass inspection first time:

  • Factory-fitted Type 2 SPD
  • Housed in a steel 4-way metal enclosure with drop-down lid
  • Fully compliant with BS EN 61439-3 and 18th Edition surge protection rules
  • Built to order – allow 3 working days for dispatch
