A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. The 203-15-20239-2 is a type of circuit breaker used to protect heavy-load circuits, particularly ones that transmit power. It is suitable for industrial and commercial applications, including for AC and DC installations, and can be used as the main breaker in a service entrance.

The 203-15-20239-2 circuit breaker features a thermal trip unit that is designed to open the breaker before an overload occurs, protecting the devices connected to it from damage due to excessive current. When the device’s current rating is exceeded, the thermal trip unit causes the breaker to open and the current to be interrupted. Once the overload is eliminated, the breaker can be reset, allowing the device to return to normal operation.

The 203-15-20239-2 also has a mechanical interlock mechanism which prevents the device from being reset before the overload is eliminated. This feature ensures that the breaker will not be reset until the current has dropped to a safe level, thereby preventing further damage.

In addition, the 203-15-20239-2 features a special low-voltage control system which can be used to detect overloads and disturbances in the electrical current. When insufficient current is detected, the voltage will drop and the breaker will open the circuit. This feature prevents equipment from being damaged due to low-voltage conditions.

The 203-15-20239-2 has an adjustable trip range which allows the user to adjust the settings to suit the particular application. This feature allows the user to set different trip levels for different types of loads. This is an important feature for applications that require a certain level of protection, as it offers the flexibility to adjust the trip level to meet the needs of the application.

The 203-15-20239-2 is designed to provide reliable and consistent protection from electrical overloads and short circuits. Its features, such as its adjustable trip range and mechanical interlock, make it a suitable option for protecting heavy-load circuits in industrial and commercial applications.
