Circuit Breakers - R21-1-1.00A-B02IV-V Application Field and Working Principle

Circuit breakers are electrical devices used to switch power supplies off and on by completing or interrupting the flow of electricity within a power circuit. R21-1-1.00A-B02IV-V circuit breakers are commonly used in automotive, marine and residential applications, and are designed to provide overcurrent protection, short circuit protection and other primary protection functions. Their structure, application field and working principle are uniquely different from other circuit breakers, let\'s learn about them.

Structure of R21-1-1.00A-B02IV-V Circuit Breakers

The R21-1-1.00A-B02IV-V circuit breakers are generally composed of four parts: frame, heat sink, electromagnetic device and insulating plate. The frame of the circuit breaker is made of a single piece of sheet metal, which is robust in structure, beautiful in appearance and safe to use. The heat sink is composed of a screw, a light-emitting diode and an aluminum heat sink. The light-emitting diode is combined with the screw to monitor the internal temperature of the circuit breaker, which is convenient for quick troubleshooting. The electromagnetic device used in the R21-1-1.00A-B02IV-V circuit breaker includes a coil, an electromagnetic core and a conductor bridge. Finally, an insulating plate is attached to the bottom of the frame to ensure safety. Depending on the applications, many different variant models are also available.

Application Field of R21-1-1.00A-B02IV-V Circuit Breakers

As well as being suitable for general electrical systems, R21-1-1.00A-B02IV-V circuit breakers are particularly suitable for automotive systems, as they can provide multiple types of protection, such as overcurrent, short-circuit, overvoltage and reverse-connection protection. In addition, due to its small size and superior performance, it can also be used in automobiles, boats and yachts with limited space. In the military and industrial applications, its high reliability and long service life make it an ideal choice for the electrical systems of military vehicles and on board of ships. It enjoys a high reputation among members of the armed forces.

Working Principle of R21-1-1.00A-B02IV-V Circuit Breakers

R21-1-1.00A-B02IV-V circuit breakers operate using a combination of principles. Firstly, when the current is too high, the heat sink has a blocking effect; this will cause the electrolyte to flow out of the gap between the heat sink and the frame, the gap will increase, and the circuit breaker will be opened. Secondly, when the current is too large, the strong magnetic force generated by the electromagnetic device will draw the conductor bridge onto the electromagnetic force, and the flow of current in the circuit will be cut off, which will cause the circuit breaker to be opened. Finally, when a short circuit occurs, the current will become too large, the temperature of the parts in the circuit breaker will rise quickly, and the temperature sensor will start the cooling system. The circuit breaker will be opened.

Conclusion

R21-1-1.00A-B02IV-V circuit breakers are widely used in automotive, marine and residential applications for overcurrent, short-circuit and overvoltage protection. These circuit breakers are easy to install, maintain and operate and provide reliable and long-lasting service.
