Circuit breakers are among the most crucial components of any electrical system, as they are designed to protect circuits from overload and other possible threats. The 219-2-4787-5 circuit breaker is no exception, and has specific features and components that make it useful in certain applications. This article describes the application field and working principle of this particular model.

The 219-2-4787-5 circuit breaker is a three-pole version of the circuit breaker and is designed for use in three-phase systems. This type of breaker is especially useful in applications where there is a high probability of phase failure or imbalance, such as in electronic and industrial applications. The breaker is also suitable for use in applications where the current ratings for each phase are different, such as in variable frequency drive (VFD) systems. Additionally, this breaker is also suitable for nonlinear loads.

The working principle of the 219-2-4787-5 circuit breaker is based on the magnetic forces generated by the current flow in the coil. As the current passes through the coil, it will generate a magnetic force which will act upon the armature and cause it to move. This motion is then used to trip the circuit breaker, which will then disconnect the circuit and thus prevent any further damage to the circuit or components. It is important to note that the trip point of the breaker is adjustable, allowing it to be used in applications where a specific threshold for current is desired.

The 219-2-4787-5 circuit breaker is rated for up to 1000 amps, and is UL listed with a voltage rating of 480 volts. It also features a short circuit current rating of 65,000 amperes, meaning that it can handle large current loads with ease. Additionally, this breaker has numerous protective features, including over-voltage, under-voltage, and over-temperature protection to ensure the safety of the circuit and the connected components. Due to these features, this circuit breaker is suitable for use in high power applications, such as power plants, factories, and large commercial buildings.

The 219-2-4787-5 circuit breaker is incredibly reliable and can be used in a variety of applications. Its features ensure that it can protect the circuit and connected components from any unwanted damage, making it an incredibly valuable piece of equipment for any professional electrician. With its adjustable trip point and numerous protective features, this particular circuit breaker is the ideal choice for any demanding application.
