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).
