Surge protective device, plug.
8/20us wave form, low residual voltage
Remote signaling port, remote alert
Hot melt flow double protection.
Connectable surge arrestor
The reaction time of less than 25 ns.
High arresting capacity
Visual status display
The maximum discharging currents (IMAX 8/20) of each line could be 30kA.
Labelled connections
Application:
Type 2 Surge Arresters provide protection against overvoltage originating from switching and the secondary effects of lightning strikes.
In order to shunt and pressure to limit indirect lightning current or other instantaneous overvoltage.
Floor distribution box of buildings
Installation:
• The type 2 arresters must install into sub-distribution boards after main distribution boards containing type 1 arresters.
• For proper operation between type 1 and type 2 arresters at least 10- 15 m cable or wire must be otherwise a decoupling coil have to install between the two devices.
