The MCB (Miniature Circuit Breaker) is a critical component in modern electrical systems. It is intended to safeguard electrical circuits from overloads and short circuits, hence assuring the overall system's safety and proper operation. MCB is widely utilized in residential, commercial, and industrial applications and has become an essential component of modern life.

Curve of Characteristics

Thermo-magnetic Expansion Characteristic Mini circuit breakers often have B, C, and D curves.
The B Curve indicates that the MCB trips between 3-5 times full load current.
The C Curve indicates that the MCB trips between 5 and 10 times full load current.
D Curve indicates that the MCB trips 10-14 times the entire load current.
The circuit breaker's relative curve diagram is shown below.
