Circuit breakers are essential components of many electrical and electronic systems, providing an essential level of safety and protection in the event of excessive system overloads or malfunctioning. The APGB121-4380-15 is an example of a circuit breaker that provides such protection for the typical home or small industrial application.

The APGB121-4380-15 is a single-pole, 15A device that functions to protect a load from overloads. Its main features include adjustable trip settings and a manual reset control. The trip setting can be adjusted by an internal switch, allowing the breaker to be set for different current levels.

Operationally, the APGB121-4380-15 works by disconnecting the power supply when it senses an overload through one of the two built-in temperature sensors. Typically, the breakers are set to trip when the temperature exceeds a maximum experience during normal operating conditions. The curves of the temperature and current characteristics can be adjusted, enabling the breaker to be modular for easy maintenance and repair.

In addition, the APGB121-4380-15 has a manual reset. When activated, it will return to its normal state, provided that the overcurrent issue has been resolved. This feature is especially useful for restarting the device after a prolonged trip or reset.

The APGB121-4380-15 is capable of working with AC and DC voltage. With its 15A current limitation and adjustable trip settings, this circuit breaker is suitable for a number of domestic and industrial applications. In domestic applications, it can protect both the house and the individuals living within it from sudden overloads and malfunctioning equipment. it can also protect industrial applications, such as pumps, motors, and other electrical equipment, from over-current damage.

In summary, the APGB121-4380-15 is an ideal choice for providing overload protection for both domestic and industrial applications. It offers high performance, adjustable trip settings, and manual reset control, making it a powerful and reliable protective device for a variety of settings.
