Circuit breakers are electrical devices designed to protect circuits from over-current or other potentially damaging events. The IULHK111-1-42-20.0-B-91 is a type of circuit breaker developed for specific applications.

This circuit breaker is most commonly used to protect circuits in high-voltage systems, such as industrial settings, power plants, and large utilities. It is designed to protect the wiring and equipment from damage due to overloads, short circuits, and other dangerous or destructive conditions.

The IULHK111-1-42-20.0-B-91 is a 3-pole circuit breaker with a rated voltage of 20.0 kV and a rated current of 42 A. It is designed to prevent both over-current and short-circuit damage. The circuit breaker works by automatically disconnecting the power supply in the event of an overload or short circuit. Once the current has been reduced to a safe level, the circuit breaker resets, allowing the power to be restored.

This circuit breaker contains several internal components which work together to provide protection from over-current and short-circuit events. The main component is the trip coil, which is used to detect current levels. When the current reaches a certain level, the trip coil activates and breaks the circuit. Additionally, the IULHK111-1-42-20.0-B-91 is equipped with a thermal protection device, which monitors the temperature of the breaker and trips the circuit if it gets too hot.

The IULHK111-1-42-20.0-B-91 is a reliable, durable, and efficient circuit breaker that is suitable for a wide range of industrial applications, including power distribution, industrial machinery, and automation systems. It is compliant with IEC/EN 60947-2 standards and has been tested to ensure maximum safety and performance. With its robust construction and high level of protection, the IULHK111-1-42-20.0-B-91 is an ideal solution for a variety of circuit protection needs.
