APPLICATION


NB1LE series leakage breaker is suitable for the leakage protection in the
line of AC 50/60Hz, rated voltage single phase 240V, three phase 240/415V and
below, rated current up to 63A. When there is human electric shock or if the
leakage current of the line exceeds the prescribed value, it will automatically cut
off the power within 0.1s to protect human safety and prevent the accident due to
the current leakage.
JXB1LE-63 series leakage breaker can protect against overload and short-circuit.
It can be used to protect the line from being overloaded and short-circuited, also
as infrequent changeover of the line in normal situation. It complies with standard
of IEC/EN61009-1 and GB16917.1.
