Circuit Breakers

The IALHPK12-1REC4-39924-150 is a circuit breaker, a device within an electrical circuit used to prevent the flow of too much current. Circuit breakers are an essential part of protecting electrical equipment and circuits from potentially damaging excessive currents. The IALHPK12-1REC4-39924-150 is a miniature circuit breaker that is generally used for lower-voltage applications.

Application Field

The IALHPK12-1REC4-39924-150 is used in a range of low-voltage applications such as lightings, motors, air conditioners, refrigeration controllers, and adjustable speed drives. It can also be used to control and protect any kind of electric equipment requiring a low voltage circuit.

Working Principle

In order to protect against over-current, the IALHPK12-1REC4-39924-150 uses an electromagnetic core containing solenoids and magnets. This core moves when an over-current occurs, cutting the power supply and preventing further damage. The current required to activate the circuit breaker is set ahead of time, and can usually be adjusted. When the current is below the set amount, the circuit breaker will remain in its closed position, allowing the power supply to flow uninterrupted.

When the current is above the set amount, the core of the circuit breaker is attracted to the magnet—causing it to open and break the electrical circuit. To reset the circuit breaker, the solenoid must be manually activated to reset the core back to its original position. This closes the circuit breaker, and power can flow uninterrupted again.

Conclusion

The IALHPK12-1REC4-39924-150 circuit breaker is essential for protecting electrical equipment from potential excessive currents. It is widely used in a variety of low-voltage applications and its working principle, based on an electromagnetic core, ensures that it is capable of reliably cutting power precisely when needed.
