IULHK112-38942-1

Circuit breakers are an important part of any electrical system. The IULHK112-38942-1 is one particular type of circuit breaker used in both residential and commercial applications. This article will discuss the application field of this circuit breaker and its working principle.

The IULHK112-38942-1 circuit breaker is ideal for applications that require a high current rating. It is commonly used to protect homes, businesses, and other structures from surges and power outages. It is also used to protect electrical lines and equipment from overloads. This circuit breaker can also be used to prevent short circuits and fires caused by faulty wiring or appliances.

The IULHK112-38942-1 circuit breaker uses a thermal-magnetic design to provide high current ratings. It is composed of a thermal element, which is a heat sensitive wire, and a bimetal disc. The bimetal disc expands when it is heated, which breaks the connection between the two wires. When the current exceeds the rated value, the thermal element begins to heat up, causing the bimetal disc to expand and trip the circuit.

It is important to note that the IULHK112-38942-1 circuit breaker also has a mechanical component. This component is what allows it to reset after it has tripped. When a circuit overloads, the mechanical component will pull the contacts apart and then reset them in a safe position.

The IULHK112-38942-1 is rated for currents up to 50 amps. It is UL 489 tested and certified to provide personnel protection. It has a National Electrical Code (NEC) rating of 10KAIC. The breaker is also equipped with a manual override switch, which allows the user to reset the breaker manually.

The IULHK112-38942-1 circuit breaker is designed to be used in a variety of applications. It is often used in residential buildings to provide protection from surges and power outages. It is also commonly used in commercial and industrial applications to protect electrical equipment from overloads.

In summary, the IULHK112-38942-1 circuit breaker is an ideal choice for a wide variety of applications. It is capable of providing high current protection and is UL 489 tested and certified for personnel protection. It also has a manual override switch which allows the user to reset the breaker manually if necessary.
