Narrow type-2 surge protection device

15 December 2015

The new Valvetrab-SEC, from Phoenix Contact, is said to be the world's narrowest type-2 surge protective device. It includes features such as durability and high performance, thanks to the use of Safe Energy Control (SEC) technology.

The disconnect device and the high short-circuit current rating of up to 50 kA offer protection for each small distribution panel at just 12 mm per channel. The type-2 protective device provides protection against severe voltage fluctuations and high stresses caused by lightning currents. 

Main system fuses can be used up to 315 A without additional backup fuses. This saves space and costs in the control cabinet. The basic element and the plug can be rotated by 180° to one another, enabling a connection with shorter cable lengths with the label remaining legible. 

All type-2 protective device product versions are pluggable and can be tested with the test device for the Checkmaster 2 surge protective devices.
