Air Break Circuit Breaker Diagram

Air break circuit breakers or air blast circuit breakers are a type of circuit breaker used to protect electrical equipment from damage due to an overload or short circuit. These breakers use compressed air to separate the contacts and interrupt the current flow. This makes them one of the most reliable and durable types of circuit breakers available.

As their name suggests, air break circuit breakers work by using air to create a gap between two contact points. When the circuit breaker is triggered, it releases a blast of air that moves quickly to separate the contact points, breaking the circuit and preventing a hazardous situation from occurring. This blast of air also helps to cool the contacts and prevent them from burning out.

In a conventional air blast circuit breaker, there is a set of `on` and `off` contact points. When the voltage in the circuit rises above the set limit, the circuit breaker is triggered and the on-contact point opens. This causes a small jet of air to move rapidly along the length of the contact and travel to the off-contact point. Here, the air pressure is sufficient enough to overcome the contact force, effectively separating the two contact points and leading to an open circuit. This effectively breaks the circuit and prevents further damage.

Air break circuit breakers usually come with a diagram to help understand their functioning. These diagrams show the various components of the circuit breaker in detail, such as its power source, the various contact points, and their positions. For example, some diagrams may also include the position of the overload relay and the mechanism by which it trips the breaker.

Air break circuit breakers are suitable for industrial applications as they have a wide range of trip characteristics and settings. They are also easy to install, as they don’t require extensive wiring. Since air break circuit breakers are highly reliable and safe, they are widely used in industrial, commercial and residential applications.

Overall, air break circuit breakers are a reliable and durable type of circuit breaker that can provide the protection that electrical installations need. With the help of a detailed diagram and careful installation, air break circuit breakers can ensure your safety and the safety of your property.
