DZ47 type mini circuit breakers daftar har ga mcb with 4p small mcb
miniature korea circuit breaker
1.application:for protecting cables and equipment against overload
and short circuit.
2.general rules for choosing MCB.
a.technical data of the network at the point considered:the
earthing systems(TNS.TNC),Short circuit current ate the circuit
breaker installation point.which must always be less than the
breaking capacity of this device.network normal voltage.
b.there are 3 curve characterristics for maganetic operation.
B curve(3-5In) protection and control of the circuits against
overloads and short circuit ;protection for people and big length
cable in TN and IT systems.
C curve (5-10In) protection and control of the circuit against
overloads and short circuit;protection for resistive and inductive
loads with low inrush current.
D curve(10-14In) protection and control of the circuit against
overload and short circuits;protection for circuit which supply
loads with high inrush current at the circuit at the circuit
closing (LV/LV transformers.breakdown lamps).
