Circuit Breakers, or CBs, are commonly used electrical devices that can protect an electrical circuit from being overloaded or short circuited.
The IULHPK111-39235-300 is an example of an AC circuit breaker with a rated voltage of 300-415VAC and a rated current of 12A. It is commonly used in residential and commercial applications where high electricity usage is anticipated, such as in places like factories, workshops, and warehouses.

CBs are designed to sense an overload, short circuit, or other fault condition, and open the circuit to protect it from further damage. To do this, the CB is equipped with a set of contacts that open and close the circuit, and these contacts are controlled by a solenoid. The solenoid is powered by the electrical current running through the circuit, and its magnetic pull activates the contacts.

The main purpose of the IULHPK111-39235-300 is to protect people and equipment from electric shock. It is designed with an adjustable protection level, so the user can set it to respond to the desired fault level before the contacts open. This adjustable protection level is what sets it apart from other types of breakers.

In addition to short-circuit protection, the circuit breaker is also equipped with a thermal overload protection feature. This feature senses when the current and voltage passing through the circuit increase beyond a certain threshold, and it will shut off the circuit before any damage can be done. This feature is important for preventing electrical fires.

Not only does the IULHPK111-39235-300 provide protection from overloads and short circuits, but it also helps increase energy efficiency. When the circuit breaker is closed, it delays the onset of current flow until after the contact points are firmly closed, which can prevent excessive current from flowing through the circuit. This helps reduce energy waste.

The IULHPK111-39235-300 is also designed to be conveniently used and maintained. It has a visible reset button that allows the user to manually reset the breaker without having to open it. It also has a removable cover, which allows easy access to the terminal connections, test points, and other components that may need to be inspected or replaced.

In conclusion, the IULHPK111-39235-300 is a reliable, efficient and easy-to-maintain AC circuit breaker that provides protection from electric shock, overloads and short-circuits. It is designed with adjustable protection level, a thermal overload protection feature, a visible reset button, and a removable cover, making it a great choice for residential and commercial applications.
