Circuit Breakers

CB123-20HB is a type of circuit breaker known for its versatility, dependability, and ability to handle a wide range of electrical loads. This circuit breaker is widely used in commercial and industrial applications, as it can protect circuits from overcurrent and short circuit while also ensuring the proper operation of equipment. The CB123-20HB is designed to break the electrical circuit if excessive current or voltage is detected, safeguarding both people and equipment from potential harm.

Application Field of CB123-20HB

CB123-20HB circuit breakers are commonly used in buildings, homes and industrial plants. They are particularly valuable in locations where a high degree of safety is required, such as in medical devices, fire prevention systems, and applications where sensitive equipment requires protection from power surges. In addition, they are typically used to provide a high level of protection in low-voltage control circuits, or when high-current overloads are detected.

Working Principle of CB123-20HB

The working principle behind a CB123-20HB is relatively simple. The circuit breaker has two main components - a fixed contact and a movable contact. As the current passes through the circuit, the movable contact is drawn outwards by its magnetic field, forcing the contact to separate from the fixed contact. This disconnects the circuit and breaks the circuit. The circuit remains broken until the current is reset or reduced to a safe level.

The CB123-20HB also has some additional features to provide further protection. One feature is a control terminal, which allows an external control signal to be sent to the circuit breaker, allowing it to be switched off remotely. It also features an over-temperature protection system, which will automatically trigger the circuit breaker if the temperature of the contacts exceeds a certain level. This helps protect both the circuit and the equipment it is connected to from potential damage.

Not only does the CB123-20HB provide superior protection and reliability, but it also features a high level of flexibility, allowing it to be used in a variety of applications. It is available in a variety of sizes and ratings, ranging from 15A - 800A, with short circuit ratings from 10kA to 65kA. This allows the circuit breaker to be adapted to many different current and voltage demands.

Conclusion

The CB123-20HB is a versatile, reliable and flexible circuit breaker, designed to provide circuit protection for a variety of applications. It features a high level of safety and protection, along with a range of features that allow it to be used in a range of environments. With its robust construction and dependable operation, the CB123-20HB is an excellent choice for those looking for reliable and safe circuit protection.
