Products
Protection of circuits against short-circuit currents, protection of circuits against overload currents switch, isolation.
EBS8B-125 circuit-breakers are used in domestic installation as well as in commercial and industry electrical distribution systems.
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 voltage.
Tripping curves:
C curve (10In + 20%)
Protection for resistive and inductive loads with low inrushcurrent.
D curve(12In + 20%)
Protection for circuits which supply loads with high inrushcurrent at the circuit losing(LV/LV transformers, breakdown lamps)
