*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).
