1. General 1.1 Function The LRM7-63 circuit-breakers are used in domestic installation as well as in commercial and industry electrical distribution systems,  it's protection of circuits against short-circuit currents, overload currents, ON/OFF, isolation,   1.2 Selection 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(10-20In) :protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers, breakdown lamps)2.
