Circuit Breakers

Circuit Breakers are a critical component in any electrical system. They provide the critical protection needed to keep people and property safe from electrocution, electrical fires, and other electrical related disasters. The 209-3-1REC5-38284-28 is a standard type link switch circuit breaker designed to provide electrical protection in residential, commercial, and industrial applications.

Application Field

This particular circuit breaker is designed for residential applications, as it can be used to protect a variety of circuits from over voltage or overload conditions. Such circuits could include HVAC systems, refrigerators, dishwashers, lighting, and other general purpose circuits. This circuit breaker is also suitable for use in light commercial applications, such as office buildings or small businesses, where lower amperage requirements are present.

Working Principle

The 209-3-1REC5-38284-28 circuit breaker is designed with a single pole switch that functions by passing a current through a contact. If the current exceeds the circuit breaker\'s threshold rating, it is designed to trip, which will disrupt the flow of current to the circuit and thus protect the circuit from overvoltage or overload conditions.

When a circuit breaker trips, it does so by using a thermal-magnetic mechanism. The thermal-magnetic mechanism uses a thermal bimetallic element that acts like a heat sensor, and a magnetic element that acts like a switch. When the current exceeds the protective threshold rating, the thermal element will expand and cause the magnetic element to trip, which will open the contact and disconnect the circuit from the current.

The 209-3-1REC5-38284-28 has a series of safety features such as automatic reset and mechanical interlock to protect both the user and the device. The automatic reset feature allows the device to reset itself after the current drops back to a safe level, while the mechanical interlock prevents resetting the device if it is not in the open or closed position.

Conclusion

The 209-3-1REC5-38284-28 is a standard type link switch circuit breaker designed to provide electrical protection in residential, commercial, and light industrial applications. It is designed to trip when a current exceeds protective threshold ratings, using a thermal-magnetic mechanism to open the contact and protect the circuit. Additionally, the circuit breaker includes several safety features such as automatic reset and mechanical interlock for user protection.
