Circuit breakers are essential components of electrical systems, providing safety protection from potentially dangerous overload and short-circuit conditions. The IULN11-1REC4-61-15.0 is a circuit breaker designed to meet the needs of medium voltage applications, offering a compact size and a variety of features and options. In this article, we\'ll explore the IULN11-1REC4-61-15.0 circuit breaker\'s application field and working principle.

Application Field

The IULN11-1REC4-61-15.0 circuit breaker is designed to provide reliable short-circuit and overload protection for medium-voltage applications. It is suitable for both indoor and outdoor environments, and is rated to meet IEEE 368 standards. The breaker also comes with UL listed certification, ensuring safety and quality. Additionally, the circuit breaker is designed for use in extreme environments including high temperature, high vibration, and EMC locations.

The IULN11-1REC4-61-15.0 circuit breaker is suitable for a variety of applications including commercial, industrial, utility substation and motor control center installations. Typical applications include panel boards, switchgear, motor control centers, busway, and transfer switches. The compact design enables ease of installation in confined spaces.

Working Principle

The IULN11-1REC4-61-15.0 circuit breaker is a three-pole device with a single power pack that provides fault and overload protection. The circuit breaker includes two sets of contacts: line and load contacts. The line contacts control the power flow between the line and load, while the load contacts control the power flow between the load and the supply.

The circuit breaker utilizes a thermal-magnetic tripping system. The thermal-magnetic element senses an overload condition and trips the breaker. In the event of a short circuit, the breaker utilizes a combination of the thermal and magnetic elements to trip the breaker. The circuit breaker is equipped with an adjustable thermal trip setting, which allows for the tripping point to be changed as needed.

The circuit breaker also includes a separate ground fault trip system, which provides fast protection against ground fault currents. The system includes a separate power pack, which provides monitoring, memory, and control functions. The power pack also provides independent protection for ground faults and other high-sensitivity applications.

In addition to the described functionality, the IULN11-1REC4-61-15.0 circuit breaker can provide additional features such as a remote contactor, load shedding, and system monitoring. These features are enabled by a combination of modular components, such as terminal blocks, relays, auxiliary contacts, and a control module. This enables the breaker to be customized to meet specific needs.

The IULN11-1REC4-61-15.0 circuit breaker is a compact, reliable, and feature-rich device for medium-voltage applications. The device provides safety and protection from dangerous overload and short-circuit conditions, and comes with UL listed certification. Furthermore, the breaker can be customized with various features to meet specific needs for installation in extreme environments.
