General
WSB3L 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.
