Circuit breakers have been used in many fields, including power systems, communications, and residential and commercial environments. One example of a circuit breaker is the IULHK1119-7400-3. It has been specifically designed for the demanding industrial market and is suitable for applications such as generators, switchgear, motor control, and industrial power systems.

A circuit breaker like the IULHK1119-7400-3 is designed to automatically detect an excessive current flow and quickly disconnect the circuit from power. It is a fail-safe device that prevents injury or damage to equipment and wires by interrupting the power supply when an overload or short circuit is detected. The circuit breaker also acts as a resetable current-limiting device, allowing heavy loads to be operated safely.

The working principle of the IULHK1119-7400-3 is quite simple. It has two main components, the trip mechanism and the hydraulic operating mechanism. The trip mechanism is designed to respond to overloads or short circuits, rapidly disconnecting the circuit from power. The hydraulic operating mechanism is designed to reset the breaker after it has tripped, restoring normal power flow.

The IULHK1119-7400-3 is rated for a maximum current of 1,000 amperes and can be used with an output voltage of up to 440 volts AC. It is designed to respond to overloads and short circuits quickly and accurately, ensuring that the circuit is not overloaded or damaged. Additionally, the breaker has an adjustable trip current range, allowing it to be set to the specific application’s current requirement.

The IULHK1119-7400-3 is a dependable industrial circuit breaker that is ideal for installations demanding maximum safety and performance. It is designed to detect and rapidly disconnect an overload or short circuit, protecting wires and equipment from damage. It also provides adjustable trip current settings, allowing it to be tailored to the specific application. When powered, the breaker quickly and precisely responds to an excessive current flow, preventing further damage and resetting itself after the overload or short circuit is removed.
