Order Information:

The ordering code for CDJD8 Smart phase & amplitude discrimination leakage relay (380V, 250A, CJ AC contactor as option) is CDJD8Q250.

n     The relay is controlled by MCU and is a smart product. When imbalanced three-phase current leads to leakage, the leakage and electric shock actions can be effected in a reliable way.

n     The relay can distinguish leakage signals from electric shock signals, and can be operated in a normal way in the case of low insulation level and great leakage current.

n     The relay can set the rated leakage action current to 300mA shift or automatic shift by means of band switch upon the request of the user.

n     When the automatic shift is set, the leakage relay can automatically select rated leakage action current value according to the leakage current.

n     The digital filtering technology is adopted for the relay for better anti-interference capability. The relay can effect correct actions in the case of lightning, harmonic wave and instant overcurrent.

n     The product effects no action in case the current drops suddenly due to leakage, and has a high operational rate. The relay can be operated in an energy-saving way and without noise, and can be operated for long time without burning the coil.

n     Digital display of leakage current as well as display of leakage protection action and failure can facilitate failure analysis. Refer to the user’s manual for the digital codes
