80A MCB is suitable for residential, commercial and industrial installations with high breaking capacity also known (MCB), is the most widely used terminal protection appliance in building electrical terminal power distribution devices. Dvolt Electric provide B, C, D three different curve products, and rated short-circuit breaking capacity can reach 10KA. You can choose MCB Breaker according to the load to be protected.
Protection of circuits against short-circuit currents,protection of circuits against overload currents,switch, isolation.
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).
