MCBs are used in motor control circuits to protect from excessive current. It can be opened or closed without any manual replacement. In the case of a fuse, once it gets blown, it must be replaced or rewired by skilled personnel. Hence, fuse is known as one of the sacrificial devices. This is the main reason why MCBs are used as an alternative to a fuse in most of the circuits. Also, whenever there is a fault in the circuit, switches in the MCB automatically shut down due to which fault can be easily detected.
MCBs are one of the most important protective devices used in electronic and electrical appliances. The MCB protects against fire hazards, electric surge and other related risks. When there is an overload in the circuit, it automatically switches off the flow of current that could lead to the occurrence of a fire or other damage.
The MCB is a type of basic electrical component that has the function of protecting the circuit against overcurrent, which may cause severe harm. The MCB is an automatic switch that opens when excessive current flows through the circuit. It can be reclosed without any manual replacement. In the case of a fuse, once a fuse has been operated, it must be replaced or rewired, depending on the type of the MCB. Hence, fuse is known as one of the sacrificial devices. This is the main reason why MCBs are used as an alternative to the fuse in most of the circuits. Also, whenever there is a fault in the circuit, the switches in.
MCBs are made up of a variety of materials that match the characteristics of the circuit. These devices can be activated at different voltages and depending on these varying voltages, MCB can be open or closed. In order for an MCB to initiate the flow of electricity in the circuit, there shouldn't be any power present across it. Thus, these devices are sometimes referred as switches or fuses capable of passing current present in the form of AC or DC voltage.
