The HYUNDAI HGM125S is a high-performance Molded Case Circuit Breaker (MCCB) engineered for reliable and robust electrical protection in industrial and commercial applications. Manufactured in Korea by HD HYUNDAI ELECTRIC, this 3-pole breaker operates on a 125A frame (125AF) with a rated current of 40A. It is designed to safeguard electrical circuits from overloads and short circuits, featuring an adjustable thermal protection setting (Ir) ranging from 0.8 to 1.0 times the nominal current for precise load matching. With a high rated insulation voltage of 1000V, an 8kV impulse withstand voltage, and an excellent breaking capacity (up to 65kA at 220/240V), the HGM125S ensures maximum safety and operational stability. It comes equipped with a push-to-trip test button and complies with stringent international standards including IEC 60947-2, CE Cat. A, and KS C 8321.
