Circuit Breakers: R21-2-15.0A-B01IH-V Application Field and Working Principle

A circuit breaker is a specialty device designed to open and close an electrical circuit, usually in response to excessive voltage or amperage along the circuit that could cause the wires or electrical components to overheat and fail. The R21-2-15.0A-B01IH-V is a particular type of circuit breaker that is used in a range of applications from residential homes to commercial settings. This article will discuss the R21-2-15.0A-B01IH-V’s application field and working principle.

Applications

The R21-2-15.0A-B01IH-V is a 15 amp, double pole, 120V, circuit breaker. This type of circuit breaker is commonly used in residential settings. For instance, it is commonly used in mobile homes, as these locations demand a specialized kind of circuit breaker due to their unique wiring needs. Additionally, the R21-2-15.0A-B01IH-V is a popular choice in commercial settings due to its durability. It is able to withstand excessive use and can easily be replaced if it malfunctions or develops issues.

Working Principle

The R21-2-15.0A-B01IH-V is equipped with a set of contacts that are designed to open or close depending on the voltage or amperage along the circuit. When current begins to exceed the breakers capacity, a bimetallic strip is triggered and breaks the circuit. This strip consists of two metals with different thermal expansion rates, and when it heats up, one metal expands faster than the other, causing the strip to bend and break the circuit. It is important to note that a circuit breaker is intended to be used only as a safety device. If the current in your circuit is higher than the circuit breaker can handle, the breaker will trip and break the circuit, protecting the wires and other components from getting damaged by electrical overload. To prevent frequent tripping of the breaker, it is important to check the load on the circuit to ensure that the load does not exceed the capacity of the circuit breaker.

Conclusion

The R21-2-15.0A-B01IH-V is a 15 amp, double pole, 120V circuit breaker that is used in a variety of residential and commercial applications. This type of breaker utilizes a bimetallic strip in order to open and close the circuit as needed. When the current in the circuit exceeds the breakers capacity, the bimetallic strip is triggered and breaks the circuit. This helps to reduce the risk of electrical overload, which can cause excessive damage to the wiring and other components on the circuit. It is important to ensure that the circuit load does not exceed the breakers capacity in order to reduce the need for frequent breaker tripping.
