IELHK11-1-72-50.0-01-V is a single-pole hydraulic magnetic circuit protector designed for reliable circuit protection and power switching in international applications. This device features a DC long delay (72) characteristic with a rated current of 50 amperes, providing precise trip-time control across a range of overcurrent conditions. The unit is VDE-approved to VDE 0660 Part 101 standards and incorporates a toggle handle with black finish and white markings for clear operational indication. With stud terminals (K designation) and standard screw terminal configuration, it delivers consistent performance across DC and dual-frequency operating modes. The protector is commonly used in industrial equipment, power distribution systems, and applications requiring accurate circuit control with extended delay response to temporary overcurrent conditions.
