Acrel ASJ20-LD1A residual current percentage light bar indication 2 programmable relay output

ACREL ASJ Series of action relay of after-current, low-voltage circuit break or low-voltage contactor can be made up for combined after-current production device, which is mainly applied for the TT and TN system distributing circuit with the alternating current 50Hz, the rated voltage 400V or below. 

ASJ Series of action relay of after-current is applied in the earth fault protection for the electric circuit, so as to prevent the equipment damage and the fire accident of electric equipment caused by the ground fault current, moreover, it also can provide indirect contact protection against the electric shock risk.

Note 3: ASJ10L-LD1A rated residual operating current IΔn is 10mA~30A continuously adjustable; Note 4: ASJ10L-LD1A limit non-driving time Δt is 0~10S continuously adjustable.
