APPLICATION
C65 Mini Circuit Breaker 1P is used in lighting distribution system or motor distribution system for protection overload and short-circuit in the system. The product is neoteris in structure, light in weight, reliable and excellent in performance. It has high breaking capacity, can trip quickly, and its case and items are adopted by high fire-resistant and shockproof plastics. The product,with long life, is mainly used in AC 50Hz/60Hz single-pole 240 or two three, four-pole 415V circuit for overload and short-circuit protection as well as for unfrequent on-and-off switching electric equipment and lighting circuit in normal case.
It conforms to the standard IEC60898,GB10953
General rules for choosing MCB
a. Technical date of the network at the point considered:The earthing systems(THS,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.
b. There are 3 curve characteristics for magnetic operation:
B curve (3-5ln) protection and control of the circuit against overloads and short-circuit ; protection for people and big length cables in TN and IT systems.
c curve (5-10ln) protection and control of the circuits against overloads and short-circuits ; protection for resistive and inductive load with low inrush current.
d curve(10-14ln) protection and control of the circuits against overloads and short-circuit ; protection for circuit which supply loads with high inrush current at the circuit closing (LV/LV
transformers, breakdown lamps).
