239-1-2717-6

Circuit breakers are a type of electrical device used to protect an electrical circuit by preventing current flow when it becomes too high. The 239-1-2717-6 circuit breaker is a type of thermal-magnetic circuit breaker that is commonly used in residential and commercial applications. It is designed to protect against short-circuit and electrical overloads.

Description of 239-1-2717-6 Circuit Breaker

The 239-1-2717-6 circuit breaker is a two-pole, one-pole adjustable circuit breaker designed to protect a single-phase, 120V circuit. The device features a common trip and a thermal-magnetic trip mechanism. It has a trip rating of 20 amperes and a maximum operating voltage of 277V.

Application Field of 239-1-2717-6 Circuit Breaker

The 239-1-2717-6 circuit breaker is an ideal choice for residential, commercial, and light industrial applications. Its small size and high performance make it suitable for use in a wide variety of applications. It is particularly useful in dealing with short-circuit and overload conditions present in modern electrical systems.

Some common applications for 239-1-2717-6 circuit breakers are residential circuit protection, commercial office building circuit protection, fire alarm circuits, and light industrial control circuits. One advantage of the device is that it can be used in applications where it will not be subject to frequent adjustment, such as fuse boxes and lighting panels.

Working Principle of 239-1-2717-6 Circuit Breaker

The 239-1-2717-6 circuit breaker operates according to the thermal-magnetic principle. The device uses a combination of electromagnetism and heat to monitor and control the current flow. The device features an electromagnet that is sensitive to current levels. When the current flowing through the circuit exceeds the rated level, the electromagnet triggers the release of a bimetallic strip which trips the switch to open the circuit.

The thermal-magnetic trip mechanism also incorporates a temperature control system. The device is designed to be able to detect when the ambient temperature around the device is too high and will automatically adjust the trip level to a higher level to protect the circuit, thus preventing further damage.

Conclusion

The 239-1-2717-6 circuit breaker is an ideal choice for residential and light industrial applications due to its small size and high performance. The device uses a combination of electro-magnetic and heat-based trip mechanisms to protect against short-circuit and overload conditions. With its adjustable trip level, the device is also suitable for applications where it will not need to be adjusted frequently, such as fuse boxes and lighting panels.
