Choosing the right surge protection device
Later this guide, you can find extensive selection
aid that will help you greatly choosing the right
surge protection device for given application. the
required interface not listed, check the following
technical properties your signal interface and com-
pare with the characteristics the surge protection
device:
Type system (telecommunications application,
MCR, etc.)
Protection class required (basic protection, fine pro-
tection, combination protection)
An unsuitable surge protection device can consider-
ably impair the application itself, for example caus-
