Circuit breakers are devices that protect electrical components from damage caused by short circuits, overloads, and other hazardous conditions. The IALHPK20-32817-200 is one such circuit breaker that provides protection for various applications. In this article, we will look at the application field and working principle of the IALHPK20-32817-200.

The IALHPK20-32817-200 is a 3-pole circuit breaker with a rated current of 20 A, and rated insulation voltage of up to 500 VAC. It is suitable for use in a variety of applications, including industrial equipment, data centers, power supply systems, and civil aviation systems. Its design makes it suitable for use in applications with extremely harsh environmental conditions, such as low and high temperatures, high humidity, and corrosive atmospheres. Moreover, the IALHPK20-32817-200 has a strong overload and short circuit protection capability, making it a convenient and reliable choice for many applications.

The working principle of the IALHPK20-32817-200 circuit breaker is based on the concept of thermal-magnetic tripping. Inside the circuit breaker, there is a thermal tripping unit and a magnetic tripping unit, both of which are capable of detecting the overload current. The thermal tripping unit uses a bimetallic strip that heats up when it encounters an overload current. This heat causes the strip to bend, which in turn causes the contacts of the circuit breaker to open and trip the circuit. The magnetic tripping unit uses electromagnets to achieve the same result. When an overload current is detected, the magnets generate a force that causes the contacts of the circuit breaker to open and trip the circuit.

The IALHPK20-32817-200 circuit breaker also comes with two additional features to optimize its performance: a reset button and a switch. The reset button is used to manually reset the circuit breaker after it has been tripped, while the switch can be used to select the current limit that best fits the application. This helps to optimize the performance of the circuit breaker and reduces the risk of a short circuit or overload.

In summary, the IALHPK20-32817-200 circuit breaker is an excellent choice for a variety of applications due to its strong overload and short circuit protection capability, reliable performance, compact design, and easy installation. It is designed to be used in harsh environments, and can be easily adjusted to fit the specific needs of the application. Its thermal-magnetic tripping mechanism together with its reset button and current limit switch make it an ideal choice for many applications.
