Introduction to Circuit Breakers

Circuit breakers are devices used in electrical wiring in order to protect electrical appliances from overloads. They are designed to open a circuit when the current flow in it exceeds a certain level, thus preventing any further damage or injury. Circuit breakers are usually found in homes and businesses and can be triggered in either manual or automatic modes.

219-4-6388-183 Application Field and Working Principle

The 219-4-6388-183 circuit breaker is a single pole, thermostatic device designed for 10A applications. It is suitable for single phase AC lighting circuits in domestic, commercial and industrial premises. The circuit breaker is also capable of intermittent duty for heavier loads where the peak current does not exceed 100A.

The 219-4-6388-183 works by using a bimetallic strip which is heated by the current flowing through it. As the current flow increases, the bimetallic strip gets hotter and eventually bends. This breaks the circuit, thereby preventing any further current flow. In addition, the circuit breaker also contains a spring-loaded handle which can be used to manually reset the breaker. This is particularly useful if the current flow is low enough to not cause the bimetallic strip to bend.

Benefits of Circuit Breakers

The use of circuit breakers provides several benefits to homeowners and businesses. Firstly, circuit breakers provide protection against over current which can cause damage to electrical appliances. Secondly, circuit breakers offer short circuit protection which can prevent electrical fires in the event of a short circuit. Lastly, circuit breakers also allow for the saving of energy, since they are able to cut off the power supply when the current is not in use.

Conclusion

The 219-4-6388-183 circuit breaker is a reliable and effective device for protecting electrical appliances in single-phase AC lighting applications. It is capable of detecting current overloads and is capable of manually resetting should the current be too low to trigger the bimetallic strip. Furthermore, circuit breakers provide homeowners and businesses with safety and energy saving benefits which make them an essential item to have installed in any home or business premises.
