Circuit Breakers

Circuit breakers are incredibly useful pieces of equipment that are found in homes, offices, and industrial settings. They are designed to protect against short-circuiting, overloads, and thermal overloads. The 209-3-8787-2 Circuit Breaker is a great example of one such device. This article will explore the 209-3-8787-2\'s application field and working principles.

Application Field

The 209-3-8787-2 is an example of a high quality, industrial grade circuit breaker. It is designed for applications in which a large current flow needs protection from short-circuits, overloads, and thermal overloads. This could include residential, industrial, or commercial environments; or applications involving high power loads.

The 209-3-8787-2 is rated at 200 Amps with a maximum voltage of 480 Volts. It is designed to operate in temperatures of -40℃ to 85℃, making it suitable for a variety of different environments. It is easily installed and maintained, and is designed for years of reliable operation.

Working Principle

At its core, the 209-3-8787-2 features a thermal-magnetic tripping device. When the current running through the device exceeds its rated capacity, a heat-sensitive element is tripped, causing the devices internal contacts to open and \'break\' the circuit. This instantly stops the flow of electricity, protecting the circuit from damage.

The thermal element is also equipped with a magnetic latch. This is used to reset the device after a tripping event has occurred. When reset, the device is placed back in its \'on\' state and electricity can once again start flowing through the circuit. This means that whilst the device is able to halt the flow of electricity in the event of an overload, it can also be quickly and easily reset and put back into operation.

The 209-3-8787-2 also features additional protective features such as an auxiliary contact. This can be used to provide a physical signal or switch other equipment when the circuit breaker is tripped. This may be used to alert operators or trigger additional circuit breakers, providing an additional layer of protection.

Conclusion

The 209-3-8787-2 Circuit Breaker is a high quality and reliable device designed for industrial applications. It features a thermal-magnetic tripping device and can be easily reset with its magnetic latching mechanism. It is capable of handling currents of 200 Amps with a maximum voltage of 480 Volts, making it suitable for a variety of applications. Finally, it features an auxiliary contact to provide additional protective features when it is triggered.
