Product Description
1. General
1.1 Function
protection of circuits against short-circuit currents, protection of circuits against overload currents, switch, isolation,
The LRM2-63 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)
