Circuit breakers are essential components in electrical systems, and the 219-2-28145-4 is an especially important model. This breaker can help protect systems from both short circuits and overloading, and its working principle and application field will be discussed here.

Application Field:

The 219-2-28145-4 breaker is designed mainly for use in large power installations where short circuits and dangerous overloading must be avoided. Specifically, it is used for the protection of any type of electrical circuit, including both AC and DC systems. Its wide range of amperage covers a current range between 0.4 and 800A. This breaker can be employed in both alternating and direct current applications, with adjustable trip characteristics and current settings.

Working Principle:

The 219-2-28145-4 breaker employs a thermal-magnetic trip system. First, the current running through the breaker is detected by the magnetic portion, which triggers the thermal portion when the current reaches a certain point. The thermal portion then heats up as the current rises, until the breaker reaches its preset limit. When this limit is reached, the breaker trips, interrupting the current and protecting the system from overload or short circuit damage.

This breaker is also fitted with a manual reset switch. This allows the user to reset the breaker without having to power off the system. Once the issue causing the breaker to trip has been eliminated, the switch can be toggled back and the breaker will go back to a normal state.

Conclusion:

The 219-2-28145-4 breaker is an essential component in electrical circuit design. Its application field covers a wide range of current levels, and its thermal-magnetic trip system ensures that the circuit is protected from overloading or short circuits. Additionally, its manual reset switch allows the user to reset the breaker without powering off the system, adding an extra layer of safety.
