ONCCY circuit breaker is used for DC rated voltage to 1000V, rated current to 63A line, for overload and short circuit protection, and can also be used as an infrequent operation of the line.Circuit breakers are used in DC applications such as communications and photovoltaic system.
In complicance with IEC/EN606947-2
It has protective function as shortage as overload, and areused in lighting distribution system in commerce and dwelling, andprotect fractional electric motors. And they also have many meritsof high protective grade(up to IP20), high breaking capacity, reliablesensitive action, convenient, multi pole assembling, long life ect.They are mainly adapted to the circuit of AC 50Hz, 250V in singlepole, 415V in double, three, four poles for protecting overload andshort circuit. Mean while, they are also used in turning on or off theelectric apparatus and lighting circuit under the normal conditions.
