The IELHK111-34474-90-V is a type of circuit breaker that is used to protect against electrical overloads. It is designed to open the circuit when the current exceeds a specified amount, thus protecting both the circuit and the components that are in it. The circuit breaker also allows the current to be controlled, which is important in order to maintain a safe and efficient electrical system.

The circuit breaker consists of two separate components: the main switching contacts and the trip coil. The main switching contacts are the two pieces of metal that have been set in motion by the trip coil. When the current passing through the circuit breaker exceeds the predetermined amount, the trip coil is activated and the main contacts open. This action interrupts the current flow, thus protecting the circuit from damage. Additionally, the circuit breaker offers protection against short-circuiting and overloading.

The IELHK111-34474-90-V is a single-pole circuit breaker, meaning it can handle only one phase of an electrical system. It is designed with an internal thermal-magnetic trip unit, which detects both the amount of current and the heat produced by the current as it flows through the circuit breaker. If either the current or heat exceeds the predetermined level, the trip unit will activate, thereby tripping the breaker. The trip unit is adjustable, allowing the user to customize the settings to protect their particular application.

In addition to protecting circuits from overloads and short-circuits, the IELHK111-34474-90-V can also be used for other applications such as power distribution, motor control, or line or load protection. The circuit breaker is suitable for most environments, as it is designed for indoor and outdoor use. Additionally, it is UL 489 listed and RoHS certified to confirm it meets certain safety standards. It is also backed by a one-year limited warranty.

Overall, the IELHK111-34474-90-V is a reliable and efficient circuit breaker that is suitable for a variety of applications. It provides protection against electrical overloads, as well as against short-circuits and overloading. The adjustable trip unit allows users to customize its settings to meet their specific application needs. Additionally, it is UL 489 listed and RoHS certified, and comes backed by a one-year limited warranty.
