The IULNK11-1-72-80.0 is a hydraulic magnetic circuit protector from the IAL/IUL/IEL/LEL series designed for reliable circuit protection and power switching in international applications. This two-pole unit operates at 80.0 A with AC 50/60 Hz delay characteristic 72 (long delay), providing impedance of 0.00123 ohms at rated current and pulse tolerance of approximately 10 times rated current. The device features 1/4-20 stud terminals (or optional M6 x 1.0 studs) with dimensions of 1.940 inches [49.28 mm] width and 1.859 inches [47.22 mm] height, and includes mounting provisions with 2X 6-32 threaded holes 0.140 inches [3.56 mm] deep. It is suitable for transformer and capacitor load applications requiring extended inrush tolerance and is available with optional barrier configurations and auxiliary switch options for enhanced circuit control and monitoring.
