Circuit breakers are important components in many electrical circuits, safeguarding the rest of the circuit from high voltage spikes or fault current. The IULHK11-25530-1 is a high quality, vented type air circuit breaker, designed for installations in a wide range of residential, commercial, and industrial environments. This article will discuss the application field and working principle of the IULHK11-25530-1 circuit breaker.

Application Field: The IULHK11-25530-1 circuit breaker is suitable for use in all kinds of residential, industrial and commercial environments. It is especially suited for use in industrial and commercial premises, with a nominal voltage of 690V and rated current up to 6250A. The circuit breaker has a high breaking capacity of 50 kA and a short-circuit current of up to 150kA.

Advantages: The IULHK11-25530-1 circuit breaker has various advantages, which makes it a popular choice for many environments. It has an adjustable over-current protection system, which allows for fine adjustment via an external adjusting device. It also has a variety of trip settings, allowing for different levels of protection. The circuit breaker has a wide rated current range and comes with the ANSI/UL489, IEC60947-2, and GB14048.2 standard certifications, ensuring a high quality product.

Working Principle: The working principle of the IULHK11-25530-1 circuit breaker is based on the operating mechanism of an electromagnet. When a fault current passes through the breaker contacts, it causes an electric field to be created between the two contacts. This electric field causes the electromagnet to be energized, which in turn causes the circuit breaker to trip. This prevents the fault current from damaging the rest of the circuit.

In order to reset the circuit breaker, the fault must first be cleared. Then, the reset button must be pressed, causing the electromagnet to be de-energized and allowing the circuit breaker to reset. This also causes the contacts to close, restoring power to the rest of the circuit.

The IULHK11-25530-1 circuit breaker is a high quality, reliable air circuit breaker designed for use in a variety of residential, commercial, and industrial environments. It has an adjustable overcurrent protection system and a wide range of trip settings, ensuring that the appliance is properly protected against faults. Furthermore, its various certifications guarantee a high quality product.
