129-L11-H-KF-25A

Circuit breakers are essential components in electrical systems. They are designed to protect electric systems from damage caused by overloading as well as short circuits. The 129-L11-H-KF-25A is a type of circuit breaker that is designed for industrial use in industrial control panel or power control systems.

This type of circuit breaker is designed to open in circuit fusing in the event of a short circuit or overload. It has two different types of operation modes; the manual mode and the automatic mode.

In the manual mode, the breaker is manually reset and in the automatic mode, it trips and then automatically resets itself. The circuit breaker also features a thermal overload protection mechanism which prevents overheating of the circuit breaker and protects the electrical components on the board from damage.

The 129-L11-H-KF-25A is rated at 25 amperes and has a maximum current rating of 250 VAC. The unit features a gas discharge tube which is designed to protect against electrical surges that are greater than 500 VAC. The circuit breaker also has an adjustable current-time curve which allows for easier and precise current-time control.

The 129-L11-H-KF-25A is mainly used in industrial control panel and power control systems. The circuit breaker can also be used in other applications where overcurrent protection is needed such as in domestic appliances, small household appliances, and other types of electric equipment.

The working principle of the 129-L11-H-KF-25A circuit breaker is based on the magnetic principle. When current flows through the coil, it creates a magnetic field which is then used to open and close the contacts of the breaker to open or close the circuit. When the current flows through the breaker, the magnetic field causes the movable contact of the breaker to open and close. This causes the circuit breaker to trip and open the circuit when the overcurrent occurs.

The 129-L11-H-KF-25A circuit breaker is a reliable and effective device that can be used in a wide range of applications. It is designed to protect electric systems from damage caused by overloading, short circuits, and electrical surges. Its adjustable current-time curve and thermal overload protection mechanism make it an ideal choice for industrial control panel and power control systems.
