Product Description

1.General
1.1 Function
protection of circuits against short-circuit currents, protection of circuits against overload currents, switch,isolation,

SRB8-63 circuit-breakers are used in domestic installation, as well as in commercial and industry electrical distribution systems.Selection

1.2Technical 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).
