Circuit Breakers

219-3-2988-938 Application Field and Working Principle

The 219-3-2988-938 circuit breakers are a special type of switch used to protect a circuit against excessive current. This switch automatically opens to disconnect the current if it exceeds a rated amount, which protects both the circuit and the user.

Circuit breakers are widely used in a variety of applications, from residential homes to industrial plants. In residential homes, they are typically used to safeguard appliances, such as air conditioners, dishwashers, and refrigerators, from overloading the electrical system. Circuit breakers are also used in industrial plants to protect expensive equipment from overload or short-circuit. For example, this type of switch may be used to protect motors, transformers, and generators from current overloads.

The working principle of the 219-3-2988-938 circuit breakers is based on an electromagnetic force. The main component of the switch is a contact point that is held open by an electromagnet. When current flowing through the circuit exceeds the rated value, it causes the electromagnet to become energized, which in turn pulls the contact point open, resulting in an interruption of the circuit. When the current returns to its normal value, the contact point is allowed to close.

The 219-3-2988-938 circuit breakers also feature a reset button that can be manually pressed to allow the current to flow again. This reset button is useful in cases when the circuit needs to be reset after an overload has occurred. Additionally, this switch also has a number of safety features, such as a thermal overload protector that automatically opens the circuit when temperatures rise above a certain value.

In conclusion, the 219-3-2988-938 circuit breakers are a essential component of any electrical system, providing protection from both overloads and short-circuits. This switch is designed to be robust and reliable, and is used in a wide variety of applications in both residential and industrial settings. The main components of the switch work together to open and close the circuit as necessary, providing a safe and reliable flow of current.
