1.Selection

Technical data of the network at the point considered:the earthing systems (TNS,TNC),short-circuit current at the circuit-breaker installation point,which must always be less than the breaking capacity ofthis device,Network normal voltage.

Tripping curves:

B curve(3-5In)

protection for people and big length cables in TN and ITsystems.

C curve (5-10In)

protection for resistive and inductive loads with low inrushcurrent.

D curve (10-14In)

protection for circuits which supply loads with high inrushcurrent at the circuit closing(LV/LV transformers, breakdown lamps).

eB is of high current limiting performance

to limit the destruction energy due to short circuit

to the greatest extent.
