Short Description:

DZ30L(DPN) residual current device has the merit of small size. It is used to protect

the circuit against overload and short circuit. When somebody gets an electrical shock

or the residual current of the circuit exceeds the fixed value, the ELCB can cut off the

power within the time of 0.1s automatically protecting the personal safety and preventing

the equipment from the fault resulted form the residual current.
