STID-63i Series RCCB Residual Current Circuit Breaker
The itme is in comply with standard of IEC61008-1,applying
to the circuit of AC 50/60Hz,230V single phase,400V three
phases or below it for industrial and mining enterprise,trade
building,commerce and family.It is mainly used for preventing
electric fire and personal casual accident caused by personal
electric shock or leakage of electrified wire net,this is a current
operated,fast leakage protector of pure electromagnetic type,
which can break off fault circuit rapidly in order to avoid
occurence
of accident.The item is precise in structure,less elements,
without auxiliary power and high working reliability.The function
of the switch won't be influenced by ambient temperature and
lightning.
The mutual inductor of the item is used to test vector
differential value of passing current,and produces a rellevant
output
power and add it to the tripper in secondary winding,if the
current of vector differential value of protected circuit of
personal electric
shock is up to or over leakage operating current,the
tripper will act and cut off so that the item will take effect of
protection.
