IELHK21-1REG4-39060-30-V

Circuit breakers are devices that are commonly used to protect electric circuits from overloads and short circuits. The IELHK21-1REG4-39060-30-V is a load break switch with an auxiliary contact that is designed for use in a range of circuits, such as those in homes, factories and industrial applications.

In the domestic environment, the IELHK21-1REG4-39060-30-V provides protection for the general electrical circuit, as well as individual circuits. This means that if an overload occurs, the circuit breaker is triggered and the power to the circuit is disconnected. The switch is mounted inside a switchboard, and when it is activated, the power is switched off and off until it is manually reset.

In addition to its uses in domestic environments, the IELHK21-1REG4-39060-30-V can also be used in a range of industrial applications. This type of circuit breaker is often used to protect industrial circuits, where large amounts of electricity are used. These circuit breakers can be used in combination with other devices, such as fuses, to provide extra protection for heavy-duty applications.

The working principle of the IELHK21-1REG4-39060-30-V circuit breaker is relatively simple. It is designed to detect an overcurrent or short circuit and disconnect the circuit automatically. The device is fitted with trip coils, which react to the current flowing in the circuit and stop the flow of electricity as soon as the current exceeds a predefined value.

The trip coils are wired in series with the load, and when a hazardous overcurrent is detected, the coil is triggered and the circuit breaker trips. This interrupts the flow of electricity in the circuit and prevents damage or destruction to the wiring or components. The switch must then be manually reset to restore power to the circuit.

The IELHK21-1REG4-39060-30-V circuit breaker also features an auxiliary contact. This contact can be used to indicate to the user when the circuit breaker has tripped. This is useful in indicating when the breaker needs to be reset, and can also provide additional protection for those applications where an audible or visual alarm would be beneficial.

In summary, the IELHK21-1REG4-39060-30-V is a load break switch that is designed to protect electrical circuits from overloads and short circuits. It is suitable for use in both domestic and industrial environments, and features trip coils and an auxiliary contact to provide protection and indicate when the breaker has tripped. When an overcurrent or short circuit is detected, the trip coils are triggered and the flow of electricity is interrupted. The circuit breaker must then be manually reset to restore power to the circuit.
