Big Amp 125A series STID-125 IP20 Protection RCCB Circuit Breaker with Pin Type Busbar 35mm wire connection
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.
