Arc Fault Detection Devices
Our AFDDs combine the function of arc fault detection, residual and over current protection (AFD+RCBO) in one compact 3 module wide unit.
Parallel arc faults may be detected by an RCBO providing the fault current is above the device tripping threshold for overcurrent or residual current protection Series arc faults cannot be detected by an RCBO, and if allowed to continue may lead to a fire.
