Circuit Breaker AFDD2-40 AFCI Arc Fault Detection Prevention Unit by Arc Monitoring AFDD+RCCB Type A 2P 40A 30mA 1Pcs(B Curve,16A 30mA)

circuit breakerThermal Circuit BreakersMagnetic Circuit BreakersGeneralAFDD2-40 incorporating MCB RCD and arc fault detection provides protection against short circuit overload leakage current and arc fault. Zero-sequence transformer of RCD detects leakage current and arc fault detects arc fault which enable the product effectively disconnect the protected circuit in case of either leakage current fault or arc fault. Applicable to AC circuit with rated current up to 32A 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 of AFDD can effectively detect and identify arc faults in its protected circuit with disabled insulation layer due to aging damaging or high humidity. The product trips and disconnects the circuit upon detection of arc faults. 1). Rated voltage (Ue) : AC230V 2). Rated frequency: 50HZ20%3). Rated insulation voltage (Ui) : 400V 4).
