What’s the best use for a 3-way mini enclosure?
It’s commonly used for small circuit protection builds such as an RCBO paired with a Type 2 SPD, often found in EV charger or solar installs.
Can I fit this alongside a consumer unit?
Yes. Its compact design and grey finish blend neatly with standard consumer units, ideal for add-on protection or retrofit applications.
Is the WME3L/32 IP rated for external use?
