Selection guide for surge protection in information technology
Easy to find!
The right surge protection for your interface.
Choosing the right surge protection in information technology is particularly challenging due to the wide range of different interfaces. The STOP-IT (Selection Tool for Protection of Information Technology) selection guide from Phoenix Contact provides support in choosing your ideal surge protection solution.
STOP-IT selection guide
The table below contains surge protective devices for data, telecommunications, measurement and control, and wireless systems, e.g., for Ethernet, ISDN, TTY (4 - 20 mA), INTERBUS, and PROFIBUS.
- The interfaces for which we recommend surge protection are listed in alphabetical order in the first column.
- The suitable surge protective device for the interface is described in the second column. Each protective device has a link to the technical data of the product.
- In the last column, application examples can be downloaded.
