Circuit Breakers are one of the most important components of an electrical system. They provide an effective way to protect electrical equipment and ensure the safety of people working with it. In this article, we will discuss the CB222-15 application field and its working principle.

The CB222-15 is a general-purpose circuit breaker. It is a device that can detect a fault current and automatically disconnect a circuit, protecting it from further damage. It is normally used in residential and commercial buildings to prevent a circuit from becoming overloaded and to protect people from electrical shock.

CB222-15 is designed to protect circuits from short-circuits, overloads and free currents. It is designed to be used in circuits with AC voltage up to the rated voltage of the breaker and frequency up to 60 Hz. It can handle short-circuit currents of up to 10kA and it is rated for 690V AC. It has a reset switch, which allows you to reset the breaker after a fault has been detected and tripped.

The working principle of the CB222-15 is based on a device called an arc fault interrupter. This device consists of two connected contact elements that open and close in response to a current or voltage imbalance. The current imbalance is measured by the arc-fault interrupter and when it reaches a certain level, it trips the circuit by opening the contacts. This interrupts the current flow, preventing further damage to the circuit.

The CB222-15 is designed to operate quickly and accurately. It has a low voltage drop, which makes it very reliable. Its arc-fault detection system is designed to be sensitive to the early stages of arc development, allowing it to trip before an overload or short-circuit can occur. It also offers over-temperature protection, allowing it to automatically trip if the temperature of the circuit rises beyond a certain level.

The CB222-15 is an effective way to protect circuits and electrical equipment against damage. It offers reliable protection against short-circuits, overloads and free currents and is designed to be used in a wide range of applications. Its arc-fault detection system is highly sensitive, allowing it to trip quickly and accurately, while its temperature protection feature ensures that it will not overheat and shut down during normal operation. All of these factors make it a valuable asset in any circuit breaker system.
