Products
Protection of circuits against short-circuit currents, protection of circuits against overload currents switch, isolation.
EBS7B circuit-breakers are used in domestic installation as well as incommercial 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:
B curve (3-5In)
Protection for people and big length cables in TN and ITsystems.
C curve (5-10In)
Protection for resistive and inductive loads with low inrushcurrent.
D curve(10-20In)
Protection for circuits which supply loads with high inrushcurrent at the circuit closing(LV/LV transformers, breakdown lamps)
