ETZBLE Series RCBO

Applicable Scope

ETZBLE RCBO is applied in the power system of AC 50Hz, single phase 230V, three phases 400v. When somebody gets and electric shock or the residual current exceeds the default value, the RCBO can cut off the power automatically to protect the personal safety and prevent the equipment from the fault resulted from the residual current. It also can protect the circuit against overload and short circuit or can be used for the unfrequent switch of the circuit undernormal condition. And extra protection functions like over voltage, under voltage can be added according to customers’ request.
It conforms to the standard IEC61009-1.GB16917.1.
