AFDD2-40 AFCI Arc Fault Detection Device Fire Prevention Unit by Arc Monitoring AFDD+RCCB Type A 2P 40A 30mA(40A 30mA)

Arc Fault Circuit BreakersAFDD2-40 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 arc fault module 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 module 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). Rated impulse withstand voltage(Uimp): 4KV 5). Rated current (In) : 6A, 10A, 16A, 20A, 25A, 32 A, 40A6). Number of poles: 1 P+N (N pole disconnectable) 7). Magnetic tripping type: B-Curve, C-Curve8). Rated service short circuit capacity (lcs) : 6KA 9). Rated short circuit capacity (lcn) : 6KA 10). Rated sensitivity: 30mA Type A Instruction: When installing this product, disconnect the upper stream power supply, and then connect the LINE and LOAD as per following steps: 1. Turn on upper strearn power supply, switch on the AFDD2-40, the illuminated push button flashes with green light at time interval 0.6s and the product starts normal service.2. Switch on the product, connect load, press test button, the product trips, the green light turns off and the illuminated push button flashes once with yellow light and goes off, which means product is at normal service.3. During normal operation of load, if the AFDD2-40 tri
