Moreday DC MCCB PV 2p 1000V 3p 1500V 80A to 400A Mould Case Circuit Breaker

A molded case circuit breaker (MCCB) is a type of electrical protection device that is used to protect electrical circuits from damage caused by overcurrents, short circuits, and ground faults. It is called a "molded case" circuit breaker because it has a molded plastic or insulating case that encloses and protects the internal components of the breaker.

An MCCB is designed to automatically interrupt the flow of electricity when it detects an abnormal or hazardous condition, such as an overload or short circuit. It consists of a movable contact and a fixed contact, which are separated by a gap known as the "arc chute." When the MCCB senses an abnormal condition, it trips, causing the movable contact to move away from the fixed contact and interrupt the flow of electricity.

MCCBs are commonly used in medium-voltage electrical systems, such as those found in industrial and commercial buildings, as well as in residential applications. They are available in a range of sizes and ratings to suit different electrical loads and applications.

MCCBs are typically used to protect electrical circuits against damage caused by overcurrents, which are currents that exceed the rated capacity of the circuit. They can also be used to protect against short circuits, which are caused by a fault in the circuit that allows a large amount of current to flow, and ground faults, which are caused by a fault in the ground wire that allows current to flow to the ground.
