Product Description
1. General
1.1 Function
The LRM9-125 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.
