IEGH66-1-62-16.0-A-21-V is a hydraulic magnetic circuit protector from the IAG/IUG/IEG/CEG/LEG series designed for low-cost power switching, reliable circuit protection, and accurate circuit control in international equipment. The unit features a single-pole configuration with a toggle handle and meets IEC spacing requirements mandatory for equipment complying with IEC specifications 601 and 950, as well as VDE specifications 0804 and 0805. It is UL Recognized as a supplementary protector per UL STD. 1077 and CSA Certified. The protector operates with a delay characteristic of type 62, which provides trip times ranging from 10 to 120 seconds at 125% rated current, 6 to 60 seconds at 150% rated current, and progressively faster response at higher overload levels. This makes it suitable for applications requiring sensitive circuitry protection, automation systems, and equipment in dense packaging environments where reliable overload and short-circuit protection is essential.
