DC Miniature Circuit Breaker I Branch Circuit Breaker DIN Rail Mount 40A Short Circuit Protector

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)
