Curve of Characteristics
Thermo-magnetic Expansion Characteristic MCB curves often have B, C, and D curves.
The B Curve indicates that the MCB trips between 3 and 5 times the total load current. It is mostly utilized in residential applications with resistive loads, including as lighting fixtures and domestic appliances with modest surge levels.
The C Curve indicates that the circuit breaker trips 5-10 times the full load current.
The D Curve indicates that the MCB trips between 10 and 14 times the overall load.
