Circuit breakers are devices that quickly shut off power in the event of a short circuit or overload. This prevents the flow of electricity from becoming too powerful, protecting wiring, appliances, and the electric grid from damage. One type of circuit breaker commonly used is the W93-X122-5 coil controlled high-speed vacuum circuit breaker.

The W93-X122-5 is a small, compact circuit breaker that is designed for use in medium and low voltage networks. It features a smart internal protection system which provides protection from overvoltage, undervoltage, low-frequency overvoltage, and current inrush. The circuit breaker also offers short-circuit tripping and interrupting protection, and is suitable for either indoor or outdoor use.

The W93-X122-5 is typically used in power distribution systems, motor control centers, and process control systems. It is compatible with a wide range of control systems, including programmable logic controllers. This type of circuit breaker is often used in heavy duty industrial applications, such as manufacturing, mining, oil and gas production, and power generation.

The working principle of the W93-X122-5 is relatively straightforward. It has a main contact, which is normally open, and a control contact, which is normally closed. When the current through the main contact increases beyond a certain level, the control contact opens and the main contact is immediately tripped. This action is triggered by a coil that is energized by an active control system.

When the main contact is opened, an arc is created between the contact surfaces. This arc is quickly extinguished due to the vacuum inside the breaker, which ensures minimal damage to the contact surfaces. The arc interrupting chamber is designed to hold the arc until it is extinguished, and the magnetic field within the chamber ensures a rapid extinguishing time.

Once the main contact is opened, the control contact is reset to its original position. This action completes the circuit breaker, allowing the current to pass through again when the active control system reaches a safe level. The W93-X122-5 is also designed to sense an overload, and will trip accordingly to prevent further damage to the system.

Overall, the W93-X122-5 is a versatile and robust circuit breaker that is suitable for a wide range of heavy duty industrial applications. It is easy to install, and has a built-in protection system that ensures safety in the event of a short circuit or overload. Its compact size makes it suitable for both indoor and outdoor use, and its reliable operation makes it an ideal choice for many applications.
