Features:
High performance varistor with thermal disconnection tripping device
35mm electrical lead rail installation
Plug-in module/base design facilitate replacement of a failed module without the need to remove system wiring etc.
8/20us wave form, low residual voltage
Protection class: Type 2, Class II.
Hot melt flow double protection.
Pole number: 3P.
With remote signaling contact for control device.
Low residual voltage and quick response.
Protection mode: L-PE.
Fault indication via red mark in the inspection window.
Application:
Protecting low-voltage consumers’ installations against indirect lightning discharges.
In order to shunt and pressure to limit indirect lightning current or other instantaneous overvoltage.
For using in the lightning protection zones concept at boundary 1-2.
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.
