DZ47LE-63 earth leakage  is used for protecting against electrical leakage in the circuit of 50Hz or60Hz or 60Hz,rated voltage single-phase 240v,three phases 415V,rated current up to 60A. If the current exceeds the fixed value, the ELCB can cut off the power within the time of 0.1s automatically to protect the personal residual current. With this function, the ELCB can protect the infrequent switch-over of the circuit under normal conditions .It conforms to IEC1009.1 .
