residual current operated circuit beaker

1. Scope of application
DZ47LE series residual current operated current breakers are mainly applied to the AC50Hz/60Hz circuit rated 230V/400V and 63A or below. They have the electric leakage (electric shock), overload, and short circuit and so on protection functions. The over voltage protection function can also be provided upon requirements. They are mainly used to protect the building illumination and power distribution system.
