Audited Supplier 1.0 SCOPE
1.1 Function
The MCB range are used in place of service cut-outs to provide overcurrent and short circuit protection.
LR6-1-63 circuit-breakers are used in domestic installation, as well as in commercial and industry electrical distribution systems.
1.2 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 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).
