Circuit breakers are devices used to protect electrical systems from damage due to over-current, over-voltage, or short circuit faults. They protect motors, transformers, and other equipment by automatically switching off the power supply to a defective circuit. The IALHK11-39399-35 is a type of circuit breaker used to protect electrical systems from over-current, over-voltage, or short-circuit faults. It is specifically designed to protect motor equipment in industrial and commercial applications.

The IALHK11-39399-35 circuit breaker is a three-phase AC circuit breaker. It uses a thermomagnetic trip system with adjustable trip settings to detect and interrupt current faults. It has an additional multi-adjustable, three-pole, auxiliary contact which can be used to control an external warning system or operate a contactor. The breaker is available in several different frame sizes, to accommodate different system voltage requirements. It can be used in systems up to 690V and currents up to 800A.

The thermomagnetic trip system is the primary mechanism used to detect and interrupt current faults. It consists of two separate elements, a bimetal strip and a magnet. When a short-circuit or overload fault occurs, the current flowing through the bimetal strip causes it to heat up. As it heats up, the bimetal strip bends and touches the magnet, which releases a spring-loaded armature to trip the breaker.

The IALHK11-39399-35 circuit breaker also has an adjustable trip setting. This allows users to adjust the current setting so that the breaker will trip at a particular predetermined current level, rather than immediately tripping on a fault. This adjustable setting is useful in applications where an over-current is expected and the breaker can be adjusted to allow the current to pass without tripping.

The IALHK11-39399-35 circuit breaker is rated for both AC and DC applications. It has a built-in undervoltage trip to protect against equipment damage caused by undervoltage, and it also has a time delay feature that allows the circuit breaker to stay closed for a predetermined period of time after the fault is cleared. This feature is especially useful in applications requiring motor startup and is also effective at preventing nuisance trips.

The IALHK11-39399-35 is a reliable and durable circuit breaker that is designed to protect industrial and commercial applications from damage caused by over-current, over-voltage, or short-circuit faults. It combines a thermomagnetic trip system with an adjustable trip setting, and a UL recognized safety rating to ensure the highest level of protection. Its robust construction and wide range of features make it an ideal solution for any industrial or commercial application.
