Introduction

Circuit breakers are essential electrical components used to protect electrical systems from damage due to power disturbances or overloads. They detect the amount of current flowing through the circuit and instantly interrupt the current in order to prevent further damage. The APGH66-35349-3 is an example of a circuit breaker, and this article will explore its applications and working principle.

Applications of the APGH66-35349-3

The APGH66-35349-3 is a 3-pole, 300 amp circuit breaker that is designed for use in residential, commercial, and industrial applications. It is capable of breaking an abnormally high fault current, and the trip unit can be programmed to shut off power if a predetermined amount of current is detected. It also has a surge arrestor which helps protect the circuit from electrical surges that could otherwise cause damage.

The APGH66-35349-3 is an ideal choice for applications where there is a high risk of short circuit or overload currents, such as commercial and industrial buildings, factories, and power plants. It is also suitable for providing protection when connecting hazardous or sensitive equipment to a power source. Furthermore, the APGH66-35349-3 is designed to be easy to install, making it a convenient option for circuit protection.

Working Principle of the APGH66-35349-3 Circuit Breaker

The APGH66-35349-3 circuit breaker is designed to automatically detect an unusually high or disruptive current flowing through a circuit and shuts it off to protect the circuit from further damage. It works by measuring the current flowing through a circuit and comparing it to a predetermined amount, known as the “trip limit”. If the current exceeds the trip limit, the circuit breaker will trip, instantly breaking the circuit and preventing further damage.

The APGH66-35349-3 also contains a thermal overload device which detects the heat generated due to prolonged excessive current. It works by shutting off the circuit if the temperature reaches a pre-determined level. This prevents the circuit from becoming damaged due to overheating.

The APGH66-35349-3 also contains an electromagnetic trip or circuit trip unit which can be programmed to trip if the current exceeds a certain level within a specific time frame. This prevents any damage to the circuit by interrupting the current before it can cause any harm.

Conclusion

The APGH66-35349-3 is a 3-pole, 300 amp circuit breaker that is designed for residential, commercial, and industrial applications. It utilizes several different methods to detect an overcurrent or short circuit, instantly tripping and breaking the circuit in order to protect it from further damage. While the APGH66-35349-3 is most commonly used in commercial and industrial settings, it is also suitable for residential applications.
