Circuit Breakers

219-4-21010-1 Application Field and Working Principle

Circuit breakers are ubiquitous in modern life and are found in virtually every home. They are used to provide protection against electric shock, over-voltage, and over-current conditions. Circuit breakers are simple to install, safe to operate, and are often used in lieu of fuses in electric circuits. In this article, we will discuss 219-4-21010-1 application field and its working principle.Circuit breakers come in a variety of designs and sizes, and are generally classified according to their voltage rating. The most common voltage rating for circuit breakers is 220-240V AC, however there are also breakers that are rated up to 600V and higher. Additionally, there are a few variations of circuit breakers that have been designed for specific applications, such as surge protection or motor control.The 219-4-21010-1 utilizes a three-phase design, which is typically used in industrial and commercial settings. The circuit breakers provide low-level protection against faults, by opening the circuit when current exceeds its rating. They are UL Listed General Purpose Circuit Breakers and can be used in most applications.The working principle of the 219-4-21010-1 is relatively simple. The circuit breaker contains an internal magnetic coil, which is energized whenever the breaker is closed. Whenever the current in the circuit exceeds its rating, the magnetic field builds up and eventually causes the contacts to separate, thus breaking the circuit.As with all breakers, the 219-4-21010-1 is designed to trip at a current level that is substantially higher than the nominal load. This is to ensure that the breaker trips before the current levels become dangerous. Additionally, if the breaker is not tripped, it will cause heat buildup, which can become a fire hazard.The applications for the 219-4-21010-1 are wide-reaching. It is often used in industrial settings, such as manufacturers and factories, for high-demand motor control and load management. Because of its three-phase design, it is also able to provide protection in higher-state multiple-pole circuits, such as those found in laundry rooms and other high-demand locations.Network and IT hardware also use circuit breakers, due to the lower amounts of power they need. The 219-4-21010-1 provides tolerance for most applications, allowing it to be used in both low voltage and high voltage circuits.Finally, the 219-4-21010-1 is also used in automotive applications, such as those found in cars and light trucks. Automotive devices like the alternator and starter motor, are able to be protected by the breaker, as they often require a large amount of current to operate.In summary, the 219-4-21010-1 is a three-phase circuit breaker that can be used in a variety of applications. It is designed to protect circuits from high currents, helping to prevent potentially dangerous and damaging scenarios. Additionally, it provides tolerance for both low voltage and high voltage circuits, making it a useful and versatile device in a wide range of applications.
