APG12-4380-19 circuit breakers are a type of protective switch used in electrical systems to protect against voltage overloads or short circuits. They are also known as overvoltage or current breakers. The main purpose of a circuit breaker is to open and close a circuit in order to protect it against excessive electrical current or voltage. In order to detect an over voltage or current, a circuit breaker senses the current flowing through the circuit and then actuates the necessary protective action.

The APG12-4380-19 circuit breakers feature a series of single-pole breakers that are designed to automatically trip at a preset rated current in order to protect the electrical circuit. The breakers also feature adjustable settings that allow the user to adjust the threshold for automatic tripping.

The APG12-4380-19 circuit breakers are mainly used in industrial, commercial and residential applications. In industrial applications, the breakers are used to protect motors and other sensitive equipment from power surges caused by lightning strikes and other current disturbances. In residential applications, they are used to protect home appliances such as washing machines and air conditioners. In commercial applications, the breakers are used to protect electrical systems from power outages and surge protection.

The working principle of the APG12-4380-19 circuit breakers is simple. It consists of an electromagnet that is activated when a predetermined amount of current is detected in the circuit. When the current exceeds the predetermined threshold, the electromagnet activates a trip solenoid that actuates the circuit breaker. This actuation opens the circuit, which is then reset by pushing the reset button.

The APG12-4380-19 circuit breakers are also equipped with a thermal trip mechanism that is triggered when the surrounding environment exceeds a specific temperature, which is typically in the range of 85°C. This mechanism is designed to protect the circuit from thermal overload.

The APG12-4380-19 circuit breakers are designed to offer reliable operation and are designed for long-term performance. They are highly efficient and durable and are easy to install. They are also designed to provide complete safety and protection for electrical systems.
