Circuit Breakers: IULHK111-1-66-30.0-E-01 application field and working principle

Circuit breakers are an essential component of any electrical production system. They protect electrical or electronic devices from being damaged by being overloaded or short-circuited. The IULHK111-1-66-30.0-E-01 is a trip device designed to protect personnel and the equipment against short-circuits and overloads. It is a three-pole circuit breaker which is ideal for industrial, commercial and domestic applications.

Application Field

The IULHK111-1-66-30.0-E-01 is designed for controlling, monitoring and tripping of three-pole circuit breakers. Its main applications include industrial processes, such as in process industries, metal factories, buildings, schools, hotels, shopping malls, and many other industrial applications. It can also be used in domestic applications for protecting households from short-circuits and other overloads caused by improper wiring.

Working Principle

The IULHK111-1-66-30.0-E-01 trip device works by detecting overcurrent in the circuit. If the current in the circuit exceeds a certain limit set by the user, the device will automatically trip and disconnect the circuit. The device has adjustable trip currents and a thermal bi-metal valve to protect it from short-circuits. It also has an LED indicator for easy monitoring. The trip current range can be adjusted from 30A to 60A.

The IULHK111-1-66-30.0-E-01 also has two additional protection functions. The first is the built-in electrical arc extinguishing system, which is designed to prevent the recurrence of arcs caused by faulty contact. The second is the built-in anti-pumping protection, which prevents the device from being continuously operated in the event of an overload.

The IULHK111-1-66-30.0-E-01 is a reliable, efficient, and safe trip device for industrial and domestic applications. With its adjustable trip currents, built-in arc extinguishing system, and anti-pumping protection, it is a great choice for any project.
