Phoenix Contact TERMITRAB complete surge protection devices

Click2Contact

A wide variety of signals are transmitted using measurement and control technology, requiring an increasingly large packing density. The TERMITRAB complete range provides surge protection starting at an overall width of 3.5 mm, representing a space saving of up to 50% in comparison with 7 mm installations. This means that the protective devices can protect up to 572 signals against surge voltages on just 1 m of DIN rail. This is made possible by Push-in connection technology and the use of particularly flat components.

The protective devices with an overall width of 6 mm also offer a large range of circuit versions and product features.

TERMITRAB complete provides visual and electrical signalling right at the protective device. The integrated disconnect feature ensures that the surge protection solution behaves safely in the event of an overload. It signals the status on each individual protective device mechanically and visually without auxiliary power. Optional transmit and receive signalling modules monitor the status of up to 40 neighbouring surge protective devices by means of a photoelectric beam. Installation is simplified as a result: no additional wiring or programming is required for the protection modules. The remote signalling sets have Push-in or screw connection. In the event of a thermal overload, the remote signalling modules notify the control room, for example, of the status in the form of a group message via a floating contact.

The product range contains products that may be installed in Ex areas up to Zone 1 with IECEX and ATEX approval.
