Circuit breakers are an important component of electrical engineering, and they are used to protect various electrical systems. The 209-3-28779-55 is a single pole concealed thermal-magnetic circuit breaker with a current rating of 15 Amps and a voltage rating of 120 Volts. This type of breaker is ideal for residential and commercial applications; some of its features include overload protection, automatic resetting, and UL classified.

The 209-3-28779-55 circuit breaker is designed with a thermal and magnetic trip unit. The thermal trip unit uses a bimetal element that senses an increased temperature when the current flow exceeds the breaker rating. When the temperature reaches a critical level, the breaker trips and interrupts the flow of the current.

The magnetic trip unit is composed of a copper cable wrapped around a coil of iron. When the current flow exceeds the breaker rating, the magnetic field generated in the coil causes the copper cable to expand, which trips the breaker and interrupts the flow of current. This type of circuit breaker is also equipped with an adjustable trip setting to provide the customer with the flexibility needed for a particular application.

The 209-3-28779-55 circuit breaker is also equipped with a manual override. This feature allows the user to manually reset the breaker and restore the power if the breaker has tripped. The breaker can be reset by simply pressing a button located on the device. Additionally, this type of breaker is UL classified, meaning it has been tested and approved to meet applicable safety standards.

The 209-3-28779-55 circuit breaker can be used in various electrical systems and applications. It is often used in residential and commercial applications such as lighting circuits, heating systems, and air conditioning units. It is also suitable for use in motor circuits, and can be used to protect motors against overloads. Additionally, this type of breaker is often used in RV and marine applications as it is resistant to UV damage.

In conclusion, the 209-3-28779-55 is a single pole concealed thermal-magnetic circuit breaker with a current rating of 15 Amps and a voltage rating of 120 Volts. It is designed with thermal and magnetic trip units to protect against overloads and short circuits. It is UL classified and can be used in various electrical systems and applications. Additionally, this type of breaker is equipped with a manual override and is resistant to UV damage.
