Circuit breakers are electrical safety devices used in industrial, commercial, and residential applications to protect people and assets from uncontrolled electrical currents. The IELHK1111-31352-1-V is a circuit breaker specifically designed for branch circuits and motor-control centers. It is a 3-phase, 3-pole UL 415-rated breaker that provides overload, short circuit, and reverse current protection.

The IELHK1111-31352-1-V consists primarily of a rotary actuator and an encapsulated trip unit. The rotary actuator is a man-machine interface that allows the user to turn the power off or reset the breaker. It also serves as a visual indication the breaker has tripped. The trip unit is the active element of the breaker and is responsible for the overcurrent, short-circuit and reverse current protection.

The working principle of the IELHK1111-31352-1-V is based on the magnetic effect of the electric current. When an overcurrent flows, the current flows through the breaker, generating a magnetic field to operate the trip unit. The trip unit then opens the contacts, interrupting the circuit and preventing damage due to overload, short circuit or reverse current.

The IELHK1111-31352-1-V is suitable for use in low-voltage branch circuits and motor control centers within commercial and industrial applications. It is designed to switch low voltage circuits up to 480 Vac with up to 200 Amps of current. It is also designed to be easy to install in a variety of enclosure types and has a wide temperature range for operation.

The IELHK1111-31352-1-V is designed to be highly reliable and compliant with strict safety standards. It is an arc-resistant breaker that provides extra protection from the arc and flash hazards associated with live circuit operations. The components of the device are designed to absorb excessive heat and reduce the risk of fire in the event of an overload.

In addition to its safety features, the IELHK1111-31352-1-V is also designed for convenient maintenance. The rotary actuator can be easily removed whenever service or adjustment is required, while the trip unit can be replaced without the need for significant wiring rework. This makes it an ideal choice for complex electrical circuits and applications where ease of access and maintenance are priority.

Overall, the IELHK1111-31352-1-V circuit breaker is a reliable and robust device designed for residential, commercial, and industrial applications. It provides overload, short-circuit and reverse current protection, while also being designed for safety and maintenance convenience. Additionally, it is UL 415-rated, making it suitable for use in a wide variety of environments and applications.
