JVL29-63 is applicable to residual operating current with rated voltage
230V/400V,frequency 50/60HZ and rated current up to 63A. It is used to perform the
human electricity shock protection as well as over current protection and short circuit
protection for line equipment in building or similar locations, it also can provide the
protection against the fire danger caused by the fault current that is resulted from the
electric equipment damage.
The circuit breaker is applicable for kinds of fields such as the industry, commerce, high
rise building, civil building, etc.
