The LELK11-39949-7-V is a hydraulic magnetic circuit protector from the IAL/CEL/LEL series designed for low-cost power switching, reliable circuit protection, and accurate circuit control in equipment for the international marketplace. This device is VDE approved to VDE 0660, part 101, and supports multiple voltage ratings (65 V to 480 V DC/AC), frequency options (DC, 50/60 Hz, and 400 Hz), and configurable pole counts (1 to 3+ poles) with current ratings ranging from 0.02 A to 300 A. The protector features multiple delay options (41–79 series) with trip time characteristics ranging from no-trip at 100% rated current to maximum trip times of 0.100 seconds at 150% overload and 0.020 seconds at 600% overload, providing flexible protection curves for diverse applications. Common applications include industrial power distribution, motor control, and equipment protection where compliance with international standards and cost-effective circuit protection are required.
