Circuit Breakers: 219-2-21646-1-V Application Field and Working Principle

Circuit breakers are safety switches, specifically designed to work with an electrical system to protect it from overloads, shorts, and surges. As the name implies, these devices break the electrical connection in order to protect the circuit, whereas a fuse will simply blow, and therefore need to be replaced. Circuit breakers are widely used in a variety of settings, and the 219-2-21646-1-V is no exception. This circuit breaker has specific applications and a specific working principle that differentiate it from other types of circuit breakers.

Application Field

The 219-2-21646-1-V circuit breaker is most often used for circuit protection of switches, relays, and motors that are connected to a circuit with a power supply voltage of 600V AC or less. It is designed to handle short-circuit current up to 100kA at 480V AC and has a sensitivity rating of 0.15A. This means that it is ideal for use in a variety of different circuits, and can be used to protect sensitive and valuable components.

Working Principle

The working principle of this circuit breaker is based on the basic concept of air break technology. An arc is created when the contacts of the circuit breaker are opened, and this arc is quickly cooled down by the air passing through the opening. The arc is then extinguished and the circuit is broken. The cooling of the arc is supported by an additional cooling system such as a fan or an exhaust, which helps to keep the temperature down and prevents the circuit back from being overloaded by too much electrical current. Additionally, the 219-2-21646-1-V also features a low-voltage detector, which detects when a low-voltage current is present and immediately trips the circuit breaker.

Conclusion

The 219-2-21646-1-V circuit breaker is designed for use in circuits with a power supply of 600V AC or less. It is designed to handle short-circuit current up to 100kA at 480V AC and has a sensitivity rating of 0.15A. This makes it ideal for protecting switches, relays, and motors from overloading and damage, as well as protecting the overall circuit from harm. Its working principle is based on the basic concept of air break technology, where an arc is created when the contacts of the circuit breaker are opened, and then cooled down by the air passing through the opening. It also features a low-voltage detector, which detects when a low-voltage current is present and trips the circuit breaker. This circuit breaker is an essential tool in the electrical world, providing invaluable protection to circuits and components.
