Application:
SG65LE 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 powerautomatically to protect the personal safety and prevent the equipmentfrom the fault resulted from the residual current. It also can protect the circuit aqainst overload and short circuit or can be used for the unfrequent switch of the circuit under normal condition. And extra protection functions like over voltage, under voltage can be added according to customers' request.
It conforms to the standard IEC1009-1. GB16917.1.
Structure
SG65LE-63 series RCBO is composed of SG65-63 high breaking MCB and residual current release. This RCBO is current operating electronic RCBO, the main parts including zero sequence current transformer, electronic panel, current leakage release and the circuit breaker with protection functions of overload, short circuit.
