Difference between MCB, MCCB, ELCB, RCCB, RCBO, RCD And MPCB || Why we use this device

RCCB and ELCB focus on protecting against ground faults and electric shocks, MCB and MCCB are designed for overcurrent protection in different capacities. MCBs are generally used for smaller loads, while MCCBs are employed for larger and more industrial applications. Choosing the appropriate circuit breaker depends on the specific needs and characteristics of the electrical system in question.
------------------------------------------------------------------
RCCB (Residual Current Circuit Breaker):
RCCB is a type of circuit breaker designed to protect against electrical shocks caused by ground faults.
It detects and trips when there is a difference in current between the live and neutral wires, indicating a leakage of current to the ground.
RCCBs are crucial for ensuring electrical safety in both residential and industrial settings.
ELCB (Earth Leakage Circuit Breaker):
ELCB is an older term for a type of residual current device (RCD) used for electrical safety.
It functions similarly to an RCCB by detecting ground faults and disconnecting the circuit to prevent electric shocks.
ELCBs are available in two types: voltage-operated (V-ELCB) and current-operated (I-ELCB). However, modern installations often use RCCBs instead of ELCBs.
MCB (Miniature Circuit Breaker):
MCB is a common type of circuit breaker used for overcurrent protection in electrical circuits.
It is designed to trip and disconnect the circuit in the event of excessive current flow due to short circuits, overloads, or faults.
MCBs are widely used in residential, commercial, and industrial applications, providing a compact and efficient means of circuit protection.
MCCB (Molded Case Circuit Breaker):
MCCB is a more robust and higher capacity circuit breaker compared to MCBs.
It is designed for larger electrical loads and higher currents, often used in industrial and commercial settings.
MCCBs offer adjustable trip settings and additional features for better customization based on the specific requirements of the electrical system.
