203-2-3934-2

Circuit breakers are electrical devices that can be used to break a circuit when a fault occurs. This protects people and equipment from potential damage by preventing an electrical circuit from continuing to conduct electricity once it has tripped. The 203-2-3934-2 circuit breaker is a two-pole type breaker that has the ability to trip on both poles at once. This makes it well suited for use in residential and commercial applications. The circuit breaker is UL 489 listed and approved for AC and DC applications up to 600 volts.

Working Principle of 203-2-3934-2

The working principle of the 203-2-3934-2 circuit breaker is based on thermal overload protection. Inside the circuit breaker there is a bimetallic element that is sensitive to both temperature and current. When the temperature rises or the current increases, the element will deform or bend and cause the breaker to trip and disconnect the power. This prevents the circuit from being overloaded and protects it from any further damage.

Application Field of 203-2-3934-2

The 203-2-3934-2 circuit breaker is designed for use in both residential and commercial applications. It can be used to protect against overloads and short circuits in lighting and appliance circuits, as well as in motor control, telecommunications, audio/video, and security systems. This type of breaker is particularly well suited for residential applications as it is UL 489 listed and can handle AC and DC applications up to 600 volts.

Conclusion

The 203-2-3934-2 circuit breaker is a two-pole breaker that is UL 489 listed and can handle AC and DC applications up to 600 volts. This type of breaker is well suited for use in both residential and commercial applications, as it is capable of tripping on both poles at once and providing thermal overload protection. It is a reliable and cost effective way to protect circuits from being overloaded or damaged.
