    *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.
    *There are 3 curve characteristics for magnetic operation:
       *B curve (3-5 In) 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-circuits; protection for resistive and
       inductive loads with low inrush current.
       *D curve (10-20 In) protection and control of the circuits against overloads and short-circuits; protection for circuits which
       supply loads with high inrush current at the circuit closing (LV/LV transformers, breakdown lamps).
