VK007 Miniature Circuit Breaker
1. General
1.1 Function
-protection of circuits against short-circuit currents
-protection of circuits against overload currents, switch
-isolation
VK007 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:
-short-circuit current at the circuit-breaker installation point, which must always be less than the breaking capacity of this device
-Network normal voltag
Tripping curves:
B curve (3-5In)
protection for people and big length cables in TN and IT systems.
C curves (5-10In)
protection for resistive and inductive loads with low inrush current.
D curves (10-14In)
protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers,
breakdown lamps)
