scope of application
LYL9-Bresidual current operated circuit breaker
is suitable for AC 50Hz, rated voltage 240V for two
poles, 415V for four poles, rated current up to 63A,
used to detect AC leakage, pulsating DC leakage,
smooth DC leakage, compound wave leakage and
high frequency leakage current up to 1kHz.When
people come’to electric shock ‘or the leakage
current of the circuit exceeds the specified value,
it automatically cuts off the faulty’power supply
in a very short time to protect the safety of people
and electrical equipment. It can also be used for
infrequent switching operations in normal
condition.
Compliant with: IEC62423,IEC61008.
