4230-T120-K0BU-32A

Circuit breakers play a critical role in electrical engineering. They are designed to open, or "break," a circuit if the current being carried through the circuit exceeds the breaker rating, protecting equipment and preventing a fire. The 4230-T120-K0/BU-32A circuit breaker is rated at 1200 Amps and utilizes its own thermal-magnetic technology in order to protect the circuit from overloads, short circuits, and ground faults.

The 4230-T120-K0/BU-32A circuit breaker is suited for a variety of applications, from heavy industrial and commercial applications to light residential applications. It also can be used in a wide variety of industrial and commercial equipment, such as motor controls, switch gear, power distribution systems, electronic equipment, and industrial tools. Additionally, the breaker can be used as a safety switch in areas where combustible materials are stored.

The 4230-T120-K0/BU-32A circuit breaker works by utilizing a thermal-magnetic operation. This works by incorporating both thermal and magnetic properties in order to determine when a fault current has reached a certain level and needs to be disconnected. The thermal component runs on a temperature sensitive device—when temperature of an operating component rises beyond a certain point, the thermal component trips and the breaker trips. The magnetic component works by detecting the current in a circuit and using electromagnets that generate a magnetic field proportional to the current—once the current reaches a certain level, the electromagnet is activated and trips the breaker. Thus, when either the thermal or magnetic components reach their limits, the breaker trips and disconnects the circuit.

The 4230-T120-K0/BU-32A circuit breaker also has advanced features that improve the quality and efficiency of its operation. The breaker features instantaneous magnetic protection—it can detect extremely fast current fluctuations, such as inrush currents from capacitors, and will provide added protection during high inrush current events. It also features a dual trip mechanism that allows for an adjustable trip point for the typical long-term current trips as well as for a shorter trip point for high inrush current trips. Additionally, the breaker also has an adjustable time-delay mechanism that can allow for a longer time delay for current trips, allowing motors to start up without tripping the circuit.

The 4230-T120-K0/BU-32A circuit breaker is a reliable, energy-saving circuit breaker that is suited for both residential and commercial applications. It provides a fast, simple, and efficient method of detecting over-currents, short circuits, and ground faults, providing added protection for equipment and preventing fires. It is designed to operate with maximum efficiency and reliability, while also providing adjustable settings to accommodate different applications, making it a versatile and reliable breaker.
