Circuit Breakers

Circuit breakers are devices used to protect mid-voltage electrical systems by detecting and responding to an overload or short circuit. They work by electrically disconnecting components that may be damaged by excessive currents. Circuit breakers work by controlling the current flow in a circuit by either limiting or limiting and tripping.

The 447-K-H-FN-400A is a type of circuit breaker specifically designed for the protection of mid-voltage distribution and control systems in industrial and commercial applications. It is rated for up to 400 Amps and is available in both molded case and draw-out case designs. The 447-K-H-FN-400A features a three-pole design with an adjustable overcurrent setting, to provide protection for electronic and electric equipment. These circuit breakers are designed to protect against damage due to voltage transients, overloads, short circuits and ground faults.

The 447-K-H-FN-400A circuit breaker works by responding to excess current in the electrical system. When the breaker senses an overload or short circuit, it will trip (open) the circuit, disconnecting the power to the affected area. It also works to protect against power surges, which can cause damage to equipment. The circuit breaker can be reset after the problem has been resolved; it will then begin to monitor the current in the circuit again and reset itself if necessary.

The 447-K-H-FN-400A is an efficient and versatile breaker, and can be used in a variety of applications. It is suitable for indoor or outdoor use, and can be used for both 120 and 240 VAC applications. They are also suitable for use with both single- and three-phase systems. The breaker is also available with an optional thermal-magnetic capability, for protection against temperature-induced overloads and starting inrush current.

The 447-K-H-FN-400A is a reliable, robust, and cost-effective circuit breaker that is perfect for use in commercial and industrial applications. It provides reliable protection against overloads, short circuits, and surge currents, and is suitable for a wide range of voltage and amperage ratings. The breaker is easy to install and maintain, and is available in a range of sizes and configurations.
