BK/MDQ-6 is a dual-element, time-delay glass fuse designed for reliable circuit protection in electrical systems. It features a physical size of ¼" × 1¼" (6.3 × 32 mm) with a glass tube and nickel-plated brass endcap construction, meeting UL standard 248-14. The fuse is rated at 250V AC with a 200A interrupting rating and exhibits a typical DC cold resistance of 0.01715 O. With time-delay characteristics, it provides protection against temporary overcurrents while withstanding sustained loads, opening at 135% of rated current within 60 minutes maximum and at 200% of rated current within 120 seconds maximum. This fuse is ideal for applications requiring selective protection in industrial control systems, power distribution, and electronic equipment where nuisance tripping must be minimized.
