Phoenix Contact: TERMITRAB Surge Protective Devices – Monitoring Surge Protection for Signal Interfaces

Signal lines are like nerve tracts in technical systems. Therefore, it is very important to protect these system parts from surge voltages caused by switching operations or lightning strikes. The surge protective devices of the TERMITRAB complete product family from Phoenix Contact enable this protection to be realized while saving space at the same time. Often, the protective components are installed in several control cabinets or in the field. This means that it is very time-consuming or even impossible to gain a permanent visual check of the protective devices on site.
