Circuit breakers are an essential safety device in any electrical system. They are designed to protect both the electrical equipment and personnel from potential harm. CR15-52-10.0A-39390-10-V is an example of a particular type of circuit breaker, designed for particular application fields and with its own particular working principles.

The CR15-52-10.0A-39390-10-V can be used in applications where a high oil level, high temperature, or both are present. It is suitable for oil-filled transformers, circuit breakers, air-insulated switches, and other high voltage equipment. In addition, it is also suitable for use in high temperature environments, such as in nuclear power plants.

The circuit breaker has a number of features that make it suitable for these applications. Firstly, it is designed to provide a wide range of protection against short circuits and overloads. This protection ensures that, in the event of an overload or short-circuit, the circuit breaker can quickly shut off the power supply, thus preventing any damage to the equipment or personnel. Secondly, it is designed with an adjustable bimetal and a differential thermal action that activate when there is a fault. This ensures that the circuit breaker can react quickly, before the fault has caused significant harm.

When the circuit breaker is triggered, it causes the contacts to rapidly separate and break the circuit, thus preventing further current flow. This means that immediately after the contacts have separated, the current is shut off completely. This is achieved through a combination of the adjustable bimetal and differential thermal action mentioned earlier. The adjustable bimetal within the circuit breaker limits the allowable current by providing a maximum current level that the circuit breaker will tolerate before tripping. The differential thermal action is an additional safety feature, as it essentially monitors the temperature of the internal components, ensuring that if the temperature rises too high, the circuit breaker trips off, preventing any further damage.

In addition, the circuit breaker also features a number of built-in tests that allow users to check whether it is working correctly. It is important to test the circuit breaker regularly to check its protection against short circuits and overloads. If the circuit breaker is not working correctly, it can not provide the necessary protection, and this could potentially lead to electric shock, fire, or physical injury. Therefore, it is important to test the circuit breaker regularly and make sure it is functioning correctly.

In conclusion, the CR15-52-10.0A-39390-10-V is a specific type of circuit breaker that is designed to be used in applications with a high oil level or operating temperature. It provides protection against short circuits and overloads, and has built-in tests that enable users to check its functioning. Therefore, it is an essential safety device that plays an important role in protecting both personnel and electrical equipment from potential harm.
