IULK111-39174-2, also known as a CE or circuit breaker, is a switch designed to break an electrical circuit when a current exceeds a predetermined level. It is a device designed to automatically disconnect an electrical circuit when it senses an overcurrent or short-circuit fault. This type of circuit breaker is designed to protect circuits from current surges and overloads when used in residential and commercial applications.

The CE circuit breaker is a form of thermal-magnetic protection, which is the combination of two protection methods: thermal protection and magnetic protection.

The thermal protection of the CE is provided by a current-sensitive heat element. In this element, a set of thermistors, connected in series and generally mounted on one or more copper and silicone substrates, sense the current through the circuit whether close or open. When the current surpasses the pre-determined maximum, the thermistors increase their resistance, increasing the temperature until they trip the breaker.

The magnetic protection is provided by a set of independent electromagnets, connected in parallel with the current element. When the current surpasses a predetermined maximum, these electromagnets activate and trip the circuit breaker. The magnetic protection is the primary form of protection as it is faster than the thermal protection, making it well-suited for short-circuits.

The CE circuit breaker is designed for use in a variety of residential and commercial applications, such as air-conditioning (HVAC) systems, motors, and surge protection systems. As the most commonly used breaker in residential settings, the CE ensures user safety and prevents damage to appliances connected to the circuit. The CE can also be used in industrial settings, where it is capable of withstanding higher current levels and more frequent trips than a standard breaker.

The CE is available in several basic sizes, all of which vary in amperage rating and voltage rating. This makes the CE a versatile device suitable for a variety of applications. It is also designed to be easy to install and replace, making it a popular choice for residential and commercial installations.

In summary, IULK111-39174-2 is a form of CE or circuit breaker designed to protect electrical circuits and components from overloads and short circuits. It is designed to automatically disconnect the circuit when the current is too high. It is available in several sizes and can be used in a variety of applications, from residential settings to industrial settings. Its easy installation and replacement features make it a popular choice for residential and commercial applications.
