Definition of Miniature Circuit Breaker and its Application in Electrical Panels
A Miniature Circuit Breaker (MCB) is an automatic electrical circuit breaker used to protect electrical circuits from excessive current and potential short circuits. These breakers are mainly used in electrical panels and power distribution systems to protect electrical equipment. Their small and compact design allows for easy installation in confined spaces and can be easily installed in electrical panels and distribution systems.
When the current exceeds the specified amount, the MCB automatically trips, preventing damage to the electrical circuit and connected equipment. These breakers are manually adjustable and can be used as protective devices for electrical equipment by measuring the electrical current and connecting to the circuit.
In electrical panels, MCBs are usually installed in groups in various series with different capacities. These breakers are commonly used to protect electrical equipment such as motors, lighting fixtures, and other electrical equipment. In case of a problem in the electrical circuits, these breakers automatically disconnect the circuit, preventing further damage to the electrical panel and its components.
