Circuit Breaker>>Miniature Circuit Breaker>>PC60N Series
1.Application
PC60N miniature circuit breaker is an all new high performance current device with the ability to disconnect short circuits of up to 10KA, which is the newest model in 21st century. PC60N miniature circuit breaker has many merits of high protective grade(up to IP20), high breaking capacity, good reliability of sensitive action, convenient multi-pole asorting, long using life ect. They are mainly used for overload and short circuit protection within the circuit of AC 50Hz, 230V in single pole, 400V in double, three & commerce. Meanwhile, they are also used in turning on or off the electric apparatus and lighting circuit under the normal condition.
