I do not have good experience with this brand of surge protector way back during Streamyx time.
The RJ11 (Phoneline) socket are completely useless to block surge.

Not sure about the electrical 3-pin point socket though, but then again usually if your house has a good fuse then it would be safe as the surge already been blocked right at the main fuse.

p/s: I had the 4-Way (Home Series) ones, not sure about Gold Series though.

those who are keen for DIY can try this step.

Sighh.. rcd is not for lightning
Mov spd baru betul.

0.01 is for water related.

bro 
just been reading this .

a good fuse  does NOT block  power surge / lightning power  surge  .  A  lightning  arrestor  or a  SPD at DB box    does  .
a fuse  is to  block overload  current .  ie    a 13 A  will blow out  if more than 13 A  flow thru .

the power surge  on phoneline/land line    is  strong . that  s  why  you had issues.
