IUGNF66-33485-50 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 applications. This device features a delay 66 characteristic with an inrush pulse tolerance of approximately 25 times rated current, providing robust protection against transient overcurrents. The trip time performance follows a defined curve where at 125% of rated current the device may trip within 50 to 700 seconds, at 150% it trips in 30 to 400 seconds, and at higher current multiples (200% to 1000%) response times decrease proportionally for faster fault clearing. The protector is suitable for equipment requiring supplementary circuit protection with precise current-time coordination, making it ideal for industrial control systems, power distribution panels, and equipment compliance with international safety standards.
