Stn60 Series RCCB 2p4p Residual Current Circuit Breaker
Application
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.
