Circuit breakers are designed to protect electrical power systems from damage due to an overload or short circuit. They are generally used in residential, commercial, and industrial settings, and some types are even used in marine and mining applications. The IULHK21-1REG4-70327-100 is a specific type of circuit breaker, designed primarily for use in high-powered industrial applications.

What is the IULHK21-1REG4-70327-100?

The IULHK21-1REG4-70327-100 is a three-phase circuit breaker that is typically used in applications where high voltage and high amperage are required, such as in oil and gas refineries and in power substations. It is designed to provide fast electrical interruption when an overload or short circuit occurs, preventing further damage and disruption to the system. The IULHK21-1REG4-70327-100 is designed for use with voltages up to 22kV (21kV maximum continuous) and current ratings up to 630A.

The Construction

The IULHK21-1REG4-70327-100 is a framed circuit breaker, meaning that it is constructed with a separate frame and breaker compartments. The frame is made of steel or aluminum and houses the main contacts, operating mechanisms, and main springs. The frame also includes a ground fault detector and trip bar, which are used to indicate when a fault or trip has occurred. The breaker compartment contains the interrupting assembly, which consists of two zinc-plated steel blades and two insulating surfaces with a pressure contact between them.

The Operating Mechanism

The IULHK21-1REG4-70327-100 is operated by a manually operated lever or a remotely operated solenoid. The lever operates by pushing the lever up, which releases the pressure contact between the two blades and initiates the electrical interruption. The solenoid operates by receiving a signal from an external source, such as an overload relay or trip-indicating device, and then releases the pressure contact between the blades when it detects an electrical fault or overload.

The Working Principle

The IULHK21-1REG4-70327-100 works on the principle of magnetic flux across a solenoid. When an overload or short circuit occurs, a magnetic field is generated in the solenoid which trips the breaker. This magnetic field causes the pressure contact between the two blades to open, which in turn initiates the electrical interruption.

Advantages of the IULHK21-1REG4-70327-100

The IULHK21-1REG4-70327-100 offers a number of advantages for use in high-powered industrial applications. Its robust design allows it to withstand high loads and withstand continuous short-circuit currents. In addition, its operating mechanism is simple and reliable, allowing it to operate in even the harshest industrial environments. Finally, the IULHK21-1REG4-70327-100 is highly economical and provides an excellent return on investment.
