The term MCB has many full forms, but out of which most relevant full form is-

MCB Full Form is – Miniature Circuit Breaker

The Miniature circuit breaker (MCB) serves a vital function in providing overcurrent protection and disconnecting services in electrical networks. Recent advances in circuit breaker technology have increased the performance and protection of the circuit breaker.

The following requirements are imposed on the circuit breaker:

First, the circuit breaker must cut off the overload current, but only when the current and, therefore, the temperature exceeds a predetermined limit. It should be remembered that the response time at low overloads is more extended than at significant overloads.

Secondly, the short circuit must be disconnected immediately. The energy transmitted through the conductor during short-circuit is so great that it is necessary to immediately break the circuit to prevent damage to the protected equipment. By protected equipment, we mean not only consumers but also a conductor, the replacement of which can result in significant capital costs and a lot of inconvenience for the user.

Third, after reducing the load to permissible limits or eliminating the cause of the short circuit, the electrical installation must be ready again for switching on and operation.

The most common electrical devices today are circuit breakers. A circuit breaker is “a mechanical switching device capable of switching on, conducting and breaking currents in the normal state of the electrical circuit, as well as switching on, conducting for a specified time and automatically disconnecting currents in a specified abnormal state of the electrical circuit, for example, in the event of a short circuit.”

The range of circuit breakers is so large. The technologies used in their production are so diverse that it is difficult to assign some circuit breakers to any specific category.

Therefore, for low-voltage circuit breakers, the following practical gradation is often used: Miniature Circuit Breakers (MCB), designed for a rated current not exceeding 125 A; tripping characteristics are usually unregulated; thermal and/or electromagnetic operating principle;

Molded Case Circuit Breakers (MCCB) is widely used in most low-voltage networks and are designed for rated currents up to 1000 A; they are also thermal and / or electromagnetic circuit breakers, in which the tripping current can be adjustable;

Circuit Breakers in an insulated case (ICCB) for low-voltage networks with increased voltage and current values.

The largest group is miniature circuit breakers. This is primarily due to the huge area of their application. In the general scheme of the electrical installation, they are installed directly near the consumers.

The circuit breaker includes the following main parts:

Contact system with an arc chute;

Electromagnetic and/or thermal release;

Free splitting mechanism.

The principle of operation of switches of this type

In the event of overloads in the protected circuit, the flowing current heats up the bimetallic plate. When heated, the plate bends and pushes a lever that acts on the free release mechanism. The tripping time decreases with increasing current.

In the case of a short circuit in the protected circuit, the current flowing through the circuit breaker’s electromagnetic coil multiplies several times; therefore, the magnetic field multiplies, which moves the core that switches the free trip lever.

In both cases, the moving contact moves away from the fixed one. The device turns off, the circuit is broken, thereby protecting the electrical circuit from overloads and short-circuit currents.

Modern circuit breakers have an improved design of the control mechanism and the free trip mechanism to reduce contact bounce. During the closing, the contacts are closed instantly, regardless of the speed of the control handle. A metal plate installed on the sidewall in the area of ​​opening contacts protects the case from burning out. In the manufacture of the case, high-quality non-combustible materials with high refractory and shockproof characteristics and high mechanical strength are used. Contact clamps, deeply embedded in the housing, provide a high degree of safety in accidental human contact with the device housing.
