MCB, MCCB, RCD, RCCD, and RCBO are all circuit breakers. They are used in homes to protect against human hazards and appliance damage. The appliances are designed to perform specific functions. It is their particular functionality that makes them different.

What is the difference between Type C and Type D circuit breakers?

C Curve means the MCB trips between 5-10 times full load current. It is used in commercial/industrial applications where there is greater chances of higher short circuit currents e.g. mainly inductive loads , fluorescent lighting. D Curve means the MCB trips between 10-14 times full load current.

What is the function of circuit breaker PDF?

The primary function of this device is to interrupt the current flow to shield the equipment and prevent the risk of fire. An electrical circuit breaker can be operated both manually and automatically to control and protect the electrical power system.
