The IELHK3111-27749-1-V is an application specific circuit breaker used in a wide variety of applications where circuit protection is critical. It is designed to automatically trip and open when a current exceeds its specified rating, preventing damage due to overload or short-circuiting.

The IELHK3111-27749-1-V is a thermal-magnetic circuit breaker, which combines two different mechanisms for protection. The thermal element uses the electrical current to generate heat, which is then dissipated by an aluminum housing. This heat causes a bimetal strip to expand and bend, slowly moving a trip bar towards the trip contacts of the circuit breaker. Once the trip bar contacts the trip contacts, the breaker will trip, interrupting the circuit and protecting it from further damage.

The magnetic element of the circuit breaker consists of an electromagnetic field produced by the current that passes through the breaker’s coil. This field pulls the trip bar towards the contact position, which trips the breaker much more quickly than the thermal element. This instant response is necessary in applications that require fast protection from over-current or short-circuiting, such as automotive circuits.

The IELHK3111-27749-1-V is designed for use in automotive and industrial applications, including furnaces, large air conditioners, pumps, motors, and other high-power potential applications. It is also used in automotive systems, such as in vehicles or on commercial trailers. The breaker’s fast trip time and low voltage drop provides reliable protection for a wide variety of applications.

The IELHK3111-27749-1-V is easy to install in panels, utilizes a low-profile design, and is compliant with international standards. The rating of the breaker can be modified to match the application requirements, providing the flexibility required in many applications.

The IELHK3111-27749-1-V is a reliable and effective way to provide circuit protection for critical applications. Its integrated thermal and magnetic elements provide fast and reliable protection from current overload and short-circuits. With its easy installation, sealed design, and international compliance, the IELHK3111-27749-1-V is an ideal solution for many automotive and industrial applications.
