Circuit Breakers

Circuit breakers are devices designed to break a circuit and protect electrical equipment from damage caused by excess current, usually resulting from a short circuit or major malfunction. The 209-2-26920-1 circuit breaker is a particular type of circuit breaker designed to disconnect a circuit when an overload current is detected. It is a low profile two pole breaker with a current rating of 20 amps and a voltage rating of 277 volts AC.

Application Field

The 209-2-26920-1 circuit breaker is ideal for a variety of applications including homes, offices, schools, and other general purpose applications. It is particularly well-suited for applications requiring a low profile device with a shallow depth. This is because the device has a depth of only 2 inches, making it easier to install in shallow walls and other tight spaces.

Other applications for the 209-2-26920-1 circuit breaker include portable equipment, panelboards, motor control centers, and electrical distribution systems. Its small size makes it suitable for protecting circuits in areas with limited space, including electrical apparatuses or machines. It is also suitable for hazardous locations, and it meets UL Recognized and ANSI/IEEE C37.04 Standard requirements.

Working Principle

The 209-2-26920-1 circuit breaker is designed to automatically switch off a circuit when an overload current is detected. It is equipped with bimetallic strips which heat up and expand when current overloads occur. When the temperature reaches a certain level, the switchable blade in the bimetallic strip breaks, triggering the circuit breaker to open and break the circuit for protection.

The bimetallic strip also helps the 209-2-26920-1 circuit breaker return to the “on” state when the overloaded current subsides. As the temperature decreases, the strip cools and contracts, allowing the circuit breaker to restore the current when the current returns to normal levels. This ensures the circuit is protected and resumed as quickly as possible.

Conclusion

The 209-2-26920-1 circuit breaker is an ideal device for a variety of applications. It performs well in areas with limited space, and it offers reliable overload protection. The device is designed to shut off a circuit when an overload current is detected, and then automatically resume the current after the overload is gone. This is a great feature that helps protect electrical equipment, while also ensuring the circuit is restored as quickly as possible.
