Order Information:
The ordering code for CDJD2 phase & amplitude discrimination leakage relay (380V, 250A, adjustable and CJC self-hold AC contactor as option) is CDJD2Q250KA.

n     CDJD2 Adjustable Leakage Relay has an additional function of adjustable leakage action current (300mA or 400mA), and the user can choose proper leakage current according to different leakage conditions and seasons of his or her region.

n     If the imbalanced three-phase current leads to leakage, the leakage and electric shock actions can be reliably effected.

n The relay can be operated in a normal way in the case of low insulation level and great leakage current

n     The relay is good at anti-interference, and can effect correct actions in the case of lightning, harmonic wave and instant overvoltage.

n     If the current drops suddenly due to leakage, the relay will effect no action so that unnecessary outage is prevented and the operational rate is high.

n     The relay is energy-saving and can be operated without noise. It can be compatible with a contactor whose coil has a working voltage of 380V or 220V (Refer to load matching wiring diagram), and can be operated for long without burning the coil.

n     The relay has a function of trial charging (Type –A and –B exclusive). It can be switched on again 20 to 30 seconds after tripping, which is safe and effortless.
