Circuit Breakers

A circuit breaker is an important electrical device used for providing protection against electrical faults and overloads. It interrupts the current flow by opening the circuit when a fault or overload occurs. Circuit breakers come in various designs, sizes, and types, and can be used in a wide range of applications. 4420.0879 is one type of circuit breaker, which is used for protecting both industrial and residential electrical systems.

Application Field of 4420.0879

4420.0879 is a two pole circuit breaker and has been designed primarily for use in household and commercial circuits. It is capable of interrupting current of up to 2 amperes, which makes it suitable for providing protection to circuits carrying lighting loads, air conditioning equipment, televisions and other heavy-duty household appliances. The 4420.0879 has a dual function, acting both as a circuit breaker and as a ground-fault circuit interrupter (GFCI). The GFCI component of the circuit is designed to cut off the power supply in case of a ground fault, such as a person coming into contact with a live wire.

Working Principle of 4420.0879

When an overload or fault occurs in the circuit, the 4420.0879 circuit breaker detects it and immediately shuts off the power supply in order to prevent further damage to the circuit. The 4420.0879 breaker has a built-in thermal fuse that detects excessive temperatures and shuts off the electrical supply in response to an overload situation. The GFCI component of the 4420.0879 works by constantly monitoring current flow through the circuit. If it senses an imbalance between the incoming and outgoing current, it trips, ceasing the flow of electricity and thus providing protection against sparking and fire caused by the exposure of live wires.

To ensure maximum safety in any application, 4420.0879 circuit breakers should always be used in tandem with other forms of protection such as circuit and overcurrent protection devices. The 4420.0879 should also be tested periodically, as required by the manufacturer, to ensure that it is still in safe working condition.

Conclusion

Circuit breakers are essential for providing protection against hazardous electrical faults and are available in a wide range of designs, sizes, and types. 4420.0879 is one type of circuit breaker, which is designed to provide protection to both industrial and residential electrical systems and has a dual function, acting both as a circuit breaker and a GFCI. A 4420.0879 is capable of interrupting current of up to 2 amperes, and its working principle involves a built-in thermal fuse that detects excessive temperatures and activates the circuit breaker, as well as a GFCI that monitors current flow and trips in case of an imbalance to provide protection against sparking and fire.
