Integrated disconnector and current limiter protect against power surges

The rollout of the fibreoptic network is in full swing. However, copper wiring is still common for internet and telecom connections in residential buildings and commercial premises. This means the connected routers are constantly exposed to overvoltage surges induced by lightning and power lines that run alongside them. The DT-TELE-WM-RJ45-PT-I by Phoenix Contact is now available on the Conrad Sourcing Platform. It reliably protects these devices, which is vital for an uninterrupted and fast internet connection.

The device protects the connected routers around the clock – no more worrying about sensitive technology during thunderstorms and over-complicated installation. The surge protector can be snapped on DIN rails or fitted into meter boxes with a flick of the wrist. Alternatively, it can be fitted to a wall using screws. And what is clever: a combination of push-in terminals and RJ45 sockets allows a versatile and user-friendly installation.

Unlike current surge protectors, which are limited in use at high transfer rates, the device does not interfere with the signals passing through it. Deutsche Telekom's VDSL, Vectoring VDSL, Super-Vectoring VDSL (SVVDSL), and G.fast tests have confirmed this. Furthermore, a built-in status indicator shows whether the device works correctly.

The device has an integrated disconnector and an electric current limiter that reduces excessive or unwanted voltage surges to harmless levels. It can even withstand a power cross, i.e., mains voltage being accidentally fed into phone lines outside a building, protecting itself and the connected router.
