LELK11-39949-15-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. The device supports multiple pole configurations (1, 2, or 3 poles) with corresponding dimension "A" measurements of 0.760 ± 0.007 inches (19.30 ± 0.18 mm) for 1 pole, 1.530 ± 0.007 inches (38.86 ± 0.18 mm) for 2 poles, and 2.280 ± 0.007 inches (57.91 ± 0.18 mm) for 3 poles, all with a panel thickness of 0.062 ± 0.005 inches (1.57 ± 0.13 mm). The protector offers multiple delay options (41, 42, 43, 49, 51, 52, 53, 59, 61, 62, 63, 69, 71, 72, 73, 79) with varying trip time characteristics across different current overload percentages, and supports DC and AC (50/60 Hz, 400 Hz) operation at various voltage ratings. This device is ideal for applications requiring VDE approval (VDE 0660, part 101) or UL recognition (UL 1077), providing cost-effective circuit protection with precise control characteristics.
