- Connects up to 2 pairs of lines that are very small in size (0.75 DIN modules).
- Protection for telephone lines and also for the digital and analogical equipment connected to these lines (fax, modem, etc).

- It has a radiofrequency receptor in order to carry out maintenance using only an emitter kit. When the RF SPD tester is applied and the protector is working, the LED flickers green. If the cartridge is damaged, the LED does not light up.
- Earthing system is introduced through a metal sheet opposite to the fixing on the DIN rail.
- In normal conditions, it remains inactive without affecting line operation or producing any leakages.
- Discharge takes place in an internal encapsulated element with no external flash.
