Visual monitoring of surge protective devices

The new TERMITRAB complete product range from Phoenix Contact offers the narrowest surge protective devices for MCR technology.

In addition to the ultra-narrow protective devices starting from an overall width of just 3.5 mm, this product range also offers versions with an overall width of 6 mm featuring mechanical signaling. Remote signaling sets, which are available as an option, monitor up to 40 protection modules. A photoelectric barrier is used for monitoring. If a surge protective device fails as a result of an overload, the integrated disconnect device closes the remote tunnel at the corresponding protective device. The photoelectric barrier for remote signaling is interrupted. The error status is forwarded to subsequent systems via the receiver module and a floating relay contact. The advantage of visual monitoring is the easy installation. It does not involve elaborate programming or additional wiring of the protective devices.
