General
1. Application: For protecting cables and equipments against overload and short circuit.
2. General rules for choosing MCB:
a. Technical data of the network at the point considered:
The earthing systems short-circuit current at the circuit breaker installation point, which must always be less than the breaking capacity of this device, network normal voltage.
B.There are 3curve characteristics for magnetic operation:
B curve (3-5In) protection and control of the circuits against length cables in TN and IT systems.
C curve (5-10 In) protection and control of the circuits against overloads and short-circuit; protection for resistive and inductive loads with low inrush current.
D curve (10-14 In) protection and control of the circuits against overloads and short-circuit; protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers, breakdown lamps).
