The BK/MDL-6/10-R is a time-delay glass tube fuse designed for circuit protection in electrical systems. It features a 6 ampere rated current at 250 Vac with an AC interrupting rating of 200 amps at 250 Vac and 10,000 amps at 125 Vac. The fuse has a physical size of 1/4 x 1 1/4 inches (6.4 x 31.7 mm) with nickel-plated brass endcaps and meets UL standard 248-14. It exhibits a typical DC cold resistance of 0.022 O, a typical melting I²t of 37.4 A²·sec, and a typical voltage drop of 0.155 V at rated current. This fuse is ideal for applications requiring time-delay protection in industrial control systems, power distribution equipment, and electronic devices where circuit protection with a delayed response to overcurrent conditions is essential.
