Semko Double Pole RCCB Circuit Breaker , IP20 Grade Power 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.
