What are the Differences between MCB, MCCB, ELCB, RCCB, RCBO, RCD and MPCB circuit breakers?

MCB, MCCB, ELCB, RCCB, RCBO, RCD, and MPCB are all types of circuit breakers, but they differ in their construction, functionality, and application. Here is a brief overview of each:

1. MCB (Miniature Circuit Breaker): MCB is a type of circuit breaker that is commonly used in homes, offices, and commercial buildings. It is designed to protect electrical circuits against overcurrents and short circuits. MCBs are available in various current ratings, and they can be easily replaced if they trip.
2. MCCB (Molded Case Circuit Breaker): MCCB is a type of circuit breaker that is used for high-current applications. It has a higher current rating than MCB and is designed for use in industrial and commercial settings. MCCBs are typically larger in size than MCBs, and they offer more features such as adjustable trip settings and remote operation.
3. ELCB (Earth Leakage Circuit Breaker): ELCB is a type of circuit breaker that is used to protect against electrical shock caused by faulty grounding or insulation. It senses current leakage and trips the circuit if it detects a current imbalance. ELCBs are commonly used in homes and offices to protect against electric shock.
4. RCCB (Residual Current Circuit Breaker): RCCB is a type of circuit breaker that is similar to ELCB, but it is more sensitive and detects lower levels of current imbalance. It is designed to protect against electric shock caused by current leakage due to a ground fault or insulation failure.
5. RCBO (Residual Current Breaker with Overload Protection): RCBO is a combination of RCCB and MCB. It provides protection against both electric shock and overcurrents. It detects current imbalance and trips the circuit if it exceeds a certain threshold. It also provides protection against overloads and short circuits.
6. RCD (Residual Current Device): RCD is a type of circuit breaker that is similar to RCCB, but it does not provide overload protection. It is designed to protect against electric shock caused by current leakage due to a ground fault or insulation failure.
7. MPCB (Motor Protection Circuit Breaker): MPCB is a type of circuit breaker that is used to protect electric motors against overloads and short circuits. It provides protection against high starting currents and thermal overloads.
