SINGLE MODULE ARC FAULT DETECTION DEVICE (AFDD)

The WAF range AFDD consists of a Type A RCBO and a Arc fault detection module in a single module DIN rail mounted unit. They combine short circuit, overload, earth leakage protection and arc fault protection and will disconnect Live and Neutral poles in the event of these faults. It could avoid various of fires caused by short circuit, circuit aging, heavy load, poor contact, fault electrical devices etc. Automatic control is realized by built-in computer chip. Its operating principle: the detected arc impulse is processed, compared and identified by electronic circuit and MCU. Once fault arc impulse which easily creates fire detected, the output will drive tripping unit to cut off the load power supply, so that the fire is prevented.
