Circuit breakers are one of the most important safety devices installed in an electrical system. They are designed to protect people, equipment, and buildings from damage caused by excessive current, or overloading, by interrupting the circuit as soon as an overload is detected. circuit breakers come in many shapes and sizes, and are suitable for applications ranging from single-phase residential wiring to commercial and industrial installations.APGH66-24257-3 is a circuit breaker manufactured by ABB. It is designed for use in a wide range of applications, from residential to light industrial applications. It features an adjustable instantaneous trip and an adjustable long time delay function. The adjustable trip settings allow the user to set the circuit breaker to trip at different current levels, based on the type of application.

The working principle of the APGH66-24257-3 circuit breaker is relatively simple. When the breaker is switched on, a small current is sent through the contacts. If the current exceeds a predetermined level, the contacts are opened and the flow of current is interrupted. The adjustable trip settings enable the user to set the current level at which the breaker will trip, depending on the requirements of the application. When the current reaches this level, the breaker will trip and interrupt the flow of current. The adjustable long time delay setting allows the user to set the amount of time that the circuit breaker will remain open before it automatically re-closes, allowing the user to select an appropriate time delay for their application.

The APGH66-24257-3 circuit breaker is suitable for applications such as lighting circuits and motor control, as well as for protection of high-end residential and light industrial electrical systems. It is designed to meet the requirements of UL489 standard for circuit breaker enclosures, and is tested to UL1077. The circuit breaker has a high short-circuit rating, making it suitable for applications with high inrush currents or short-circuit conditions. In addition, it features a mechanical lockout, which prevents resetting without mechanically unlocking the breaker. This makes the circuit breaker particularly suitable for applications where a high level of safety is required.

In summary, the APGH66-24257-3 is a circuit breaker designed for a wide range of applications. It features adjustable trip settings and long time delay settings, allowing for precise control of the breaker’s response time. The breaker is UL489 compliant and features a high short-circuit rating and a mechanical lockout, making it suitable for applications requiring a high level of safety.
