Perfect fit in the Contactum consumer unit.
For the price these are unbeatable. They are solid units unlike the frame only designs from other brands. And they match the RCBOs from Contactum so also visually a professional look.

Neat alternative

Fills a spare but also covers a spare node on the busbar so you can have a full length busbar without leaving exposed live copper for the unwary.
