Circuit breakers are indispensable electrical devices used in many industries to protect against overload of electrical systems. They interrupt the flow of current in a circuit as a safety measure. A circuit breaker with a part number APL111-21469-9 is a Class C magnetic trip, 3-pole unit designed to provide a reliable means of protection to an electrical system. This type of circuit breaker will trip when the current in the circuit exceeds a specified level and the device will reset. The operation of this system is based on the principles of electromagnetism, which is the study of how electric fields interact with magnetic fields.

The working principle of the APL111-21469-9 circuit breaker is quite simple and straightforward. The device includes a solenoid-actuated trip assembly with an adjustable magnetic trip. The electromagnetic field generated by the current carrying conductors will interact with the magnetic trip in the device. Depending on the amount of current flowing through the circuit, a mechanical armature will be actuated and will trip the circuit breaker.

The APL111-21469-9 circuit breaker is designed for use in domestic, commercial and industrial applications. It is ideal for the protection of low-voltage electrical systems as it can respond quickly to prevent excessive amperage or short-circuiting. In addition to its protection against overloads, this device can also be used to protect against short-circuiting, resulting in a more reliable and safer electrical system.

This circuit breaker also includes features such as self-test switch, manual override switch, and a visible trip indicator to indicate when the device has been tripped. The device also contains a pressure contact disconnect bar, which secures and releases the circuit breaker when the power is connected or disconnected.

Because of its reliable protection capabilities and wide range of applications, the APL111-21469-9 circuit breaker is one of the most popular and widely used circuit breakers on the market. It provides a simple yet effective way to protect your electrical system from overload and short circuit currents, making it an ideal choice for any electrical system.
