1.1 Tính năng

Protection of circuits against short-circuit currents, protection of circuits against overload currents,

switch, isolation.

1.2 Lựa chọn thiết bị

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 of this device,

Network normal voltage.

Tripping curves:

B curve (3-5In)

protection for people and big length cables in TN and IT systems.

C curve (5-10In)

protection for resistive and inductive loads with low inrush current.

D curve (10-14In)

protection for circuits which supply loads with high inrush current at the circuit closing

(LV/LV transformers, breakdown lamps).
