6KA 230V Singi Residual Current Circuit Breaker , mccb circuit breaker
APPLICATION
SG65LE-63 earth leakage circuit breaker is applied in the power system of AC 50Hz,single phase 230V,three phases 400V.When somebody gets and electric shock or the leakage current exceeds the default value, the ELCB can cut off the power automatically to protect the personal safety and prevent the equipment from the fault resulted from the leakage current.
The ELCB also can protect the circuit against 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 earth leakage circuit breaker is composed of SG65-63high breaking mini circuit breaker and current leakage release. The ELCB is current electronic current leakage circuit breaker, the main parts include zero sequence current transformer, electronic panel, current leakage release and the circuit breaker with protection functions of over load, short circuit.
