Type 2 surge protector BR-30FU 4P series

class IIfor electrical installationsremote signaling

The surge arrestors BR-30FU meet the type 2 requirement class according to IEC 61643-11. 35mm electrical lead rail installation 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. • In areas where storms are frequent, it is strongly recommended to install additional protection systems.
