IALNK1-27748-5

Circuit breakers are designed to protect an electrical circuit from damage caused by a short circuit or an overload. They are essential devices in any electrical system and come in a variety of designs, configurations and functions.

The IALNK1-27748-5 is a medium-voltage circuit breaker type HSCB (high-speed circuit breaker) designed for protection against short circuits, overloads and over voltage. This type of circuit breaker is used in many industrial and commercial applications, where it is necessary to provide high-speed protection of high-voltage circuits.

The IALNK1-27748-5 is a three-pole circuit breaker with a rated voltage of 380V AC and a rated frequency of 50Hz. It is designed to withstand a short circuit current of up to 20kA. This type of circuit breaker is equipped with a thermal-magnetic trip unit, which uses an electromagnet to detect an abnormally high current in the circuit and to trip the breaker when the current exceeds the rated value.

The thermal-magnetic trip unit is also equipped with a thermal element, which is used to detect an abnormally high temperature in the circuit caused by an overload. When the temperature exceeds a certain set point, the thermal element is activated and trips the breaker. The thermal element is also helpful in detecting a ground fault, as it will also detect an imbalance in the current in the ground wire.

The IALNK1-27748-5 circuit breaker is designed to provide fast and reliable protection against short-circuits, overloads and over voltages. It is used in a wide range of applications, including motor control centers, building systems, electric heaters, motor drives, and machine tools. The circuit breaker is designed to meet UL standard 489 and is rated for use up to 20kA. It also has a readily available spare parts and provides an excellent lifetime performance.

In conclusion, the IALNK1-27748-5 is a three-pole medium-voltage circuit breaker type HSCB, which is used to provide fast and reliable protection against short circuits, overloads and over voltages. With its high-speed trip unit and thermal element, the circuit breaker provides excellent protection for high-voltage circuits in a variety of industrial and commercial applications.
