MCU 40A Type A RCBO & PME Fault

The MCU 40A Type A RCBO & PME Fault Unit is a compact, all-in-one electrical protection solution designed for safe and compliant electric vehicle charger installations. This 6-way metal distribution board features an integrated O-PEN device and Type A RCBO, offering reliable protection against overcurrent, earth faults, and PME (Protective Multiple Earthing) faults in single-phase setups.

Ideal for use with any EV charger that lacks built-in PME protection, this unit is fully compatible with residential and commercial EV charging systems, including those working alongside solar PV, wind turbines, and battery storage systems. It supports dynamic load balancing, ensuring optimal energy usage without compromising safety.

Compliant with OZEV Government Grant requirements when installed with a Zappi Hub, the MCU 40A RCBO unit is a future-ready, regulation-compliant choice for safe, efficient EV infrastructure.
