Circuit Breakers

Circuit breakers are essential components in electrical power systems. They protect electrical equipment from dangerous over-currents, by quickly opening the circuit and preventing damage or destruction of the system.

The 209-2-1-51-2-9-100 is an example of a circuit breaker, specifically designed for use in industrial applications. It is a two-pole circuit breaker with adjustable trip settings, providing improved protection against overload and short circuiting. The adjustable trip settings give the user the ability to customize the protection based on the loading requirements of the system.

Working Principle

The 209-2-1-51-2-9-100 circuit breaker uses an electromechanical design to detect and protect against over-currents. It is equipped with a voltage sensing device, which detects a change in current and triggers the relays, thus opening the circuit. When the current rises above the preset limit, the contacts within the circuit breaker open and the circuit is broken, thus preventing damage to connected equipment.

The 209-2-1-51-2-9-100 also has a thermal overload protection feature. This feature monitors the internal temperature of the circuit breaker, and if it reaches unsafe levels due to prolonged or excessive current, the contacts are opened and the circuit is broken. This prevents equipment from being damaged due to overheating.

Application Field

The 209-2-1-51-2-9-100 is suitable for use in a variety of industrial applications. It is commonly used in manufacturing and production plants, as well as in commercial and industrial buildings. It is also suitable for use in automation systems and control panels, due to its adjustable trip settings and thermal overload protection feature.

The 209-2-1-51-2-9-100 is also suitable for use in low and medium voltage applications. It is designed for use with W-type circuits, and is rated up to 600V AC. It is also UL489 certified, meaning it meets the most stringent safety requirements for electrical circuits.

Conclusion

The 209-2-1-51-2-9-100 circuit breaker is an ideal choice for a variety of industrial applications. It is equipped with a voltage sensing device, adjustable trip settings, and thermal overload protection, all of which combine to provide superior protection against dangerous over-currents. It is also suitable for both low and medium voltage applications, and is UL489 certified for added safety.
