Geya Afdd3- 40 Arc Fault Circuit Breaker Afdd Afci Arc Fault Protection Preventing (AFDD) Protection Fire Prevention Unit by Arc Monitoring Factory Sell

Overview:
AFDD3-40 incorporating MCB, RCD, and arc fault detection module, provides protection against short circuit, overload, leakage current, and arc fault. Zero-sequence transformer of RCD detects leakage current, and the arc fault module detects arc fault, which enables the product effectively disconnect the protected circuit in case of either leakage current fault or arc fault.
Application:
AFDD3-40, applicable to AC circuits with rated current up to 40A, provides protection against arc fault, overload, short circuit, and leakage current fault happened to branch circuits in lighting distribution and power distribution system.
The arc fault detection module of AFDD3-40 can effectively detect and identify arc faults in its protected circuit with a disabled insulation layer due to aging, damaging, or high humidity. The product trips and disconnects the circuit upon detection of arc faults.
