C45 6KA MCB Mini circuit breaker

C45 Circuit breaker is used in lighting distribution system or motor distribution system for protecting overload and short circuit in the system. Our circuit breaker is neoteric in structure, light in weight, reliable and excellent in performance. The circuit breaker's frame and parts adopt plastics of high fire resistant and shockproof. The product, with long life, is mainly used in AC 50Hz/60Hz single pole 240V or two, three, four poles up to 415V circuit for overload and short circuit protection, as well as for unfrequently switching on&off electric equipment and lighting circuit in normal case. The products comply with IEC 60898 & GB10963-1999.

Curve B: (3~5 In) protect and control circuit against overload and short circuit; protect people and length cables in TN and IT systems.



Curve C:(5~10 In) protect and control circuit against overload and short circuit; protect resistive and inductive loads with low inrush current.



CurveD: (10~20 In) protect and control circuit against overload and short circuit; protect circuits which supply loads with high inrush current when the circuit closing.
