Circuit breakers are electrical devices that protect electrical systems from damage caused by overcurrent and power surges. They are used to protect people, equipment, and structures from high voltage and current damage. In layman\'s terms, circuit breakers are similar to a fuse, in that when a circuit is overloaded, the breaker automatically trips and cuts off the power to the area.The 412-K54-FN2-5A circuit breaker is a type of circuit breaker designed for use in power distribution or protection applications. It is a combination of two smaller breakers, allowing for high voltage or current protection in a single device.The 412-K54-FN2-5A is a miniature, direct-mount, air circuit breaker. It is designed for use in applications such as motor circuits, transfer switches, control circuits, and generator control panels. It is specifically designed to provide protection for 100A circuits at 300VAC. The circuit breaker is rated for 400A at 240VAC, with an interrupting capacity of 25kAIC.The 412-K54-FN2-5A circuit breaker is a combination of two smaller breakers, both of which can be used independently. The main breaker is rated for either 15A or 20A at 240VAC and is used as the primary source of protection for the circuit. The secondary breaker is rated for 10A at 225VAC and serves as the back-up breaker in the event of an overload or surge on the main breaker. The combination of the two breakers ensures a reliable and efficient protection system.The working principle of the 412-K54-FN2-5A circuit breaker is straightforward. When an over-current or a power surge occurs, the two breakers work together to break the circuit. First, the main breaker trips and cuts off the power, then the secondary breaker trips and cuts off the power. This protects the circuit from damage caused by excess current or power surges.The 412-K54-FN2-5A circuit breaker is an essential component for any power distribution or protection application. It is designed to provide reliable and efficient protection for 100A circuits at 300VAC. The combination of the two smaller breakers ensures a reliable protection system, while the design offers ease of installation and maintenance. The 412-K54-FN2-5A circuit breaker is a great solution for any power distribution application.
