Circuit Breakers

Circuit breakers are electrical components that disconnect the power supply when the current reaches a certain level or in case of a fault. A standard circuit breaker works by sensing the current’s flow and sensing any overvoltage, undervoltage, short-circuit, or overload condition. In such cases, the circuit breaker will automatically trip, immediately disconnecting the power supply. The circuit breaker with part number 229-2-35793-20 is a good example of a common circuit breaker.

Application Fields

Circuit breakers are commonly used in many different application fields, such as power distribution, HVAC systems, motor control, lighting, and more. In the field of power distribution, they are used in order to protect electrical equipment from damage due to short-circuits or overloads. In HVAC systems, circuit breakers are used to protect the unit’s motor from damage caused by phase-to-phase short circuit or overload. In motor control, circuit breakers are used in order to protect motors from damage due to overloads. In addition, they can also be used as a safety device, in order to protect people from the hazards of electric shock.

Working Principle

The working principle of a circuit breaker is quite simple. It is essentially a spring-loaded switch, which will open up when the current exceeds the designated level. As the current passes through the circuit breaker, it will heat up a bimetallic strip located inside of it. As the strip heats up, it will expand, eventually pushing the spring-loaded contacts open to trip the circuit breaker. As the contacts open, the supply of electricity is disrupted, which will result in the power output being cut off.

Circuit breakers are incredibly important when it comes to protecting people and equipment from the potential dangers of electricity. The circuit breaker with part number 229-2-35793-20 is an example of a common circuit breaker, and it can be used in a wide variety of applications. It is reliable, safe, and effective, making it an ideal choice for any electrical application.
