LELK111-39950-20-V is a hydraulic magnetic circuit protector designed for low-cost power switching, reliable circuit protection, and accurate circuit control in international equipment applications. The device is VDE approved to VDE 0660, part 101, and supports multiple voltage ratings including 65V, 80V, 125V, 250V, 300V, and 277V/480V configurations with DC and AC (50/60 Hz) operation. It offers configurable delay characteristics (ranging from 41 to 79 delay codes) with trip time ranges from 0.004 seconds to over 700 seconds depending on current overload percentage, and supports current ratings from 0.02 A to 300 A. The protector is available in 1, 2, or 3-pole configurations with panel thickness of 0.062 ± 0.005 inches (1.57 ± 0.13 mm) and dimension A varying by pole count. These devices are ideal for industrial control systems, power distribution equipment, and applications requiring both thermal and magnetic protection with international compliance.
