Circuit Breakers

A circuit breaker, also known as an interrupter switch, is an electromechanical device designed to protect a circuit from damaging currents caused by overloads or shorts. Circuit breakers are typically used to provide a margin of safety for both the electrical components and the individuals using them. Many circuit breaker types are available, depending on the application field and the type of circuit it will protect.

209-1-31988-15 Application Field and Working Principle

209-1-31988-15 circuit breaker is a thermal-type breaker designed for use in industrial, commercial, and residential applications. It is rated for a maximum voltage of 120/240V and operates with a maximum current of 20A. The 209-1-31988-15 is a single-pole breaker and is typically used to protect circuits with a load of up to 20A, including lighting circuits, heating circuits, and appliance circuits.

A 209-1-31988-15 breaker operates by detecting excessive current draw in the protected circuit and breaking the circuit at its terminals. This is accomplished through the use of a bimetallic strip which consists of two different metals bonded together. The different metals are chosen based on their differing temperature coefficients. When current is passed through the bimetallic strip, the two metals expand at different rates. This expansion causes the strip to bend or move which trips a switch within the breaker, thereby opening the circuit.

The 209-1-31988-15 breaker has a special feature that allows it to be tripped manually by pressing the reset button. This feature is beneficial in cases where the circuit breaker may need to be reset after an overload or short circuit. The circuit can then be reset without having to turn off the power to the entire system. Additionally, the 209-1-31988-15 can be reset without removing the breaker from the panel, making it more convenient and time-saving.

Conclusion

The 209-1-31988-15 is a single-pole circuit breaker designed for use in industrial, commercial, and residential applications. It operates by using a bimetallic strip to detect excessive current draw in a protected circuit and trip the circuit at its terminals. The 209-1-31988-15 also has a manual reset button which allows it to be tripped without having to turn off the power to the entire system. As such, this breaker allows for quick and convenient resetting of circuits while providing the necessary protection against overloads and shorts.
