CE CB Approved 4p Breaker-Protector RCCB Residual Current Operated Circuit Break
WSB2L series MCB is one of updated type MCCBs researched and developed by the company by using advanced design and manufacture technology internationally.
WSB2L series RCCB are suitable for distribution lines with ac 50Hz, rated working voltage of AC240/400V and rated current up to 63A and below. When the person gets electric shock or the leakage current of the network exceeds the specified value, the leakage circuit breakers can quickly cut off the fault power supply in a very short time to protect the safety of the person and the electrical equipment. The RCCB have the advantages of advanced structure, reliable performance and compact volume.The shell is made of high impact resistance and flame retardant material. The RCCB have the functions of overload, short circuit and leakage protection. They are mainly used for overload, short circuit and leakage protection of office buildings, residential buildings and distiller buildings, distribution lines and equipment. They can also be used for infrequent conversion of lines under normal conditions.
