A client has a very expensive ground-source heatpump installed.
The place is in an exposed rural position - phone line is overhead, 11kV to local Tx overhead too. The machine is connected to the 'net through a separate interface box.

Last year all the circuit boards were damaged during a stormy period. It also took out the internet interface ~ though strangely enough, the broadband box and everything else connected to it all survived...

Specifying transient protection is a bit out of my field..
Can anyone suggest suitable kit for the Cat5 coming into the machine, and its 50A 1ph feed? Is this the sort of stuff that the likes of RS carry, or is it more specialist than that?
