About this product
The four-module version of the MD1, for three-phase distribution boards. It protects all three phases plus neutral at a higher continuous operating voltage of 420V, which is what a 415V three-phase supply needs.
Each module carries its own status window, so you can see at a glance which one has taken a hit. Modules are individually replaceable.
Fit this at the origin of a three-phase installation, and a second Type 2 device closer to sensitive equipment if the cable run is long.
