Product Description

    Brief introduction

       DZ47LE series leakage circuit breaker is suitable for the circuit of AC 50HZ ,rated working voltage 230V /400V and rated current 60A , to make indirect contact protection to the human beings and protect the circuit against over current in buildings or other similiar locations as well,also to prevent fire acident caused  by contionuous ground fault current due to the damage of over-current protection equipment.In addition,the leakage circuit breaker with over voltage caused by fault of power grid.

 

   Application

       This series of productsis more and more used for stand -by protection against ground fault and electric shocks by idirect   contact and indirect contact in the low voltage distributioin system.The products are in conformity with such standards as GB16917 and IEC 61009.
