Circuit Breakers

A circuit breaker is an electrical device designed to protect an electrical circuit from damage caused by an overload or short circuit. It does this by automatically interrupting the flow of electricity when the electrical current crosses a predetermined threshold. The 209-2-30432-50 circuit breaker is a molded case circuit breaker that has been developed to meet the UL 89 standard for safety, and can be used in both residential and commercial applications.

Application Field

The 209-2-30432-50 circuit breaker can be used in a variety of applications, including residential, commercial, and industrial, offering users a secure and reliable solution for protecting their electrical systems and equipment. The breaker can be used in both indoor and outdoor installations, in branch circuits, feeder circuits, and in distribution centers. It is suitable for use in air conditioning, heating, lighting, motors, and other electrical equipment, as well as in emergency systems and hazardous locations.

Working Principle

The 209-2-30432-50 circuit breaker works on a simple principle. It is designed with a thermal-magnetic trip unit that monitors the current and temperature of the circuit. When the current or temperature exceeds the breaker\'s rating, the trip unit is triggered and the breaker trips, interrupting the flow of electricity to the circuit and effectively preventing further overload or short-circuit damage. The 209-2-30432-50 circuit breaker is designed with internal gaskets and seals that protect it against environmental factors, and can withstand temperatures up to 150°C.

The breaker is also designed with adjustable overload and short circuit ratings, allowing users to adjust the settings in order to protect their circuits from overloads and short circuits. The 209-2-30432-50 also features an instantaneous trip setting which is designed to trip the breaker at an even higher current or temperature setting. This allows the breaker to provide a greater level of protection in applications where the current or temperature is known to exceed the breaker’s ratings.

Conclusion

The 209-2-30432-50 circuit breaker is a highly reliable device that is designed to protect residential, commercial, and industrial electrical systems and equipment from overloads and short circuits. It is designed with adjustable overload and short circuit ratings as well as an instantaneous trip setting, allowing users to customize the protection of their system. With an internal gasket and seal, the 209-2-30432-50 can be safely used in both indoor and outdoor applications and is suitable for a variety of applications including air conditioning, heating, lighting, motors, emergency systems, and hazardous locations.
