Circuit breakers are electrical devices designed to safely protect electrical circuits from excessive currents, overheating, short circuits, overloads, or potentially dangerous ground faults. The IULHK111-1-42-7.50-01 is an example of a circuit breaker designed specifically for use in industrial applications. This article will discuss the application field and working principle of the IULHK111-1-42-7.50-01 circuit breaker.

The IULHK111-1-42-7.50-01 circuit breaker is designed for low voltage, high amperage applications, making it suitable for a wide range of industrial applications. It is rated for AC 4P (3 phase) 380V, 400V, 415V, 440V, and 480V, and DC 2P for 500V and 800V. It has an adjustable current rating from 50A to 5000A, making it suitable for a variety of different applications. It is certified by IEC, UL, and CE, making it suitable for use in North America, Europe, and Asia.

The IULHK111-1-42-7.50-01 circuit breaker has several built-in safety features. It has an adjustable trip current setting, allowing the user to set the breaker to open when a certain amount of current is exceeded. It also has an adjustable trip voltage setting, allowing the user to set the breaker to open when a certain voltage is exceeded. The breaker also has an overload protection feature, which prevents the breaker from opening when the current rating is exceeded. Finally, it has a ground fault protection feature, which prevents the breaker from opening when a dangerous ground fault occurs.

The working principle of the IULHK111-1-42-7.50-01 circuit breaker is fairly simple. When the power is switched on, the contacts in the breaker close and the current is allowed to flow. If an overload or short circuit occurs, the breaker detects the excessive current flow and opens the contacts in order to disconnect the circuit and prevent further damage or injury. In the case of a ground fault, the breaker detects the difference between the two lines and opens the contacts in order to disconnect the circuit and prevent further damage or injury.

The IULHK111-1-42-7.50-01 circuit breaker is an ideal solution for industrial applications that require low voltage, high amperage protection. It is certified for use in North America, Europe, and Asia, and is designed with several built-in safety features. Its adjustable current and voltage settings make it suitable for a wide variety of different applications, while its overload and ground fault protection features ensure that the circuit breaker will remain safe under all conditions.
