Molded Case Circuit Breaker is known as MCCB. It is an electrical safety device that guards against overcurrents and short circuits in power distribution networks, shielding electrical equipment and circuits. To protect the security of electrical installations and guard against equipment damage brought on by electrical faults, MCCBs are frequently employed in industrial, commercial, and residential applications.

• The internal components of MCCBs are housed in a molded case enclosure, which is typically constructed of a non-conductive material. The case offers insulation and defense from the elements.
• An MCCB's primary duty is to stop the flow of current when it exceeds a certain limit. The MCCB trips to open the circuit and stop the flow of electricity when an overcurrent (excessive current) or short circuit occurs in the circuit.
• A built-in tripping mechanism in MCCBs reacts to several kinds of defects. The two most common kinds of tripping mechanisms are as follows:
• Most MCCBs have programmable options that let you alter how the device behaves while on a trip. These parameters, including the current rating, overload protection, and short circuit protection, can be changed to correspond to the protected circuit's unique requirements.
