Intelligent Power Supply Surge Protector

Product Details

The intelligent power supply surge protector can meet the type 2 requirement class according to IEC 61643-11. These devices protect low-voltage consumer systems from overvoltages of all types and are available in single-pole to four-pole versions. The use of high-performance varistors permits a rapid response time and a low protection level, without any line follow current. If circumstances are uncertain and there is a risk of fire from an overload, the internal cut-off unit disconnects the arrestor from the mains if necessary. In addition, the QR code printed on the arrestor allows disary.

Features:

Connectable surge arrestor
High arresting capacity
Visual status display
Available with optional remote signalling
Vibration-proof
Simple standard hat rail mounting
Labelled connections
