History of Hyundai Corporation

Hyundai Electric Corporation is one of the largest manufacturers of electrical equipment globally, operating in numerous countries. Established in 1977, the company evolved over decades into a leading player in the electrical industry worldwide.

Initially, Hyundai collaborated with foreign companies such as LG in South Korea and Siemens in Germany to procure the necessary electrical equipment. However, in 1984, spurred by the rapid growth of the electrical industry in South Korea, Hyundai decided to independently produce electrical equipment.

Since then, Hyundai has experienced rapid growth, becoming one of the largest manufacturers of electrical equipment globally. Hyundai utilizes advanced technologies to produce high-quality and competitively priced products, including transformers, power distribution systems, motors, and multimeters.

Today, Hyundai Electric Corporation has representatives in over 100 countries worldwide and continues to produce electrical equipment for various industries, including oil and gas, aluminum, mining, steel, automotive, and more, with over 3,000 employees.

Types of Hyundai Miniature Circuit Breakers:

۱٫ Hyundai HIBD Miniature Circuit Breaker – Old Type:
The Hyundai HIBD Miniature Circuit Breaker is a type of push-button miniature circuit breaker used in applications such as electronic and industrial equipment. It features two states, ON and OFF, and operates by pressing the button, delivering a blow to the breaker, thereby activating it. The HIBD Miniature Circuit Breaker also has soldered terminals for connection to a circuit board or other electronic equipment. With its compact and portable design, it is precision-engineered and suitable for industrial and electronic equipment applications.
