Surge protectors with telephone jack

Phone jack

— the presence of a connector for connecting the telephone network in the design of the surge protector. This function allows you to use the device to protect the telephone line (against impulses, voltage surges, etc. — depending on the protection capabilities available in the filter itself); such protection can be especially useful for the stable operation of a fax or modem. Note that the minimum number of telephone connectors is two: an input for connecting a line and an output to the device.
