Circuit breakers are an important safety device used to prevent the flow of electricity in the event of an electrical fault. This helps reduce the risk of fire or other hazards caused by a surge or overload of electricity. The IULHK11-39572-17 is a type of circuit breaker used in electrical and industrial control systems.

The IULHK11-39572-17 circuit breaker is a three-pole, thermal-magnetic molded-case breaker that is designed for use in air-conduction environment, with rated current up to 60A. This type of breaker is compatible with electrical and industrial automation systems and can be used in a variety of locations including control panels, distribution boards, and other similar applications. It features a range of overload and short-circuit protective mechanism, as well as a range of additional auxiliary functions.

The working principle of the IULHK11-39572-17 circuit breaker is based on the thermomagnetic effect. This is a combination of two different methods for protecting the circuit from overcurrent and short circuit faults. The thermal element is used to detect a sustained overcurrent and trip the breaker, while the magnetic element operates in a much faster time frame and is used to detect and trip a sudden short circuit fault. By combining the two elements, the circuit breaker can provide effective protection against both types of fault.

The IULHK11-39572-17 circuit breaker is designed to operate at temperatures up to 105 degrees Celsius, and is capable of withstanding a short circuit current of up to 10 kA. It also features a wide range of auxiliary functions, including auxiliary contacts, auxiliary N/C and N/O contacts, and a manual test switch. This makes it ideal for use in industrial rated applications, such as motor control and pump control.

The IULHK11-39572-17 circuit breaker is an excellent choice for a range of industrial or electrical applications. Its thermomagnetic operation, wide range of auxiliary functions, and short- circuit withstand capability make it suitable for use in a variety of situations. In addition, its robust design ensures it is capable of providing a reliable and effective protection against overcurrent and short-circuit faults.
