Phoenix Contact TERMITRAB range boasts space-saving surge protection

Oct. 13, 2017 – With the TERMITRAB complete product range, Phoenix Contact says it now offers the narrowest surge protective devices on the market.

They are suitable for MCR applications starting from an overall width of 3.5 mm, which means that the protective devices can protect up to 572 signals against surge voltages on just one meter of DIN rail, says the company. The integrated disconnect device promises safe behaviour in the event of overload. It signals the status on each individual protective device mechanically without auxiliary power. Optional remote signalling modules monitor the status of up to 40 neighbouring surge protective devices by means of a photoelectric barrier. Phoenix Contact says installation is simplified as a result — no additional wiring or programming is required for the protection modules. The surge protective devices are available with Push-in connection technology as well as screw connection. Versions are also available with knife disconnection and for Ex applications.
