BK/MDL-V-2-R is a time-delay glass tube fuse with axial leads designed for circuit protection in electrical systems. It features a 1/4 x 1 1/4 inch (6.4 x 31.7 mm) physical size with nickel-plated brass endcaps and is rated for 2A at 250Vac with an AC interrupting rating of 100A at 250Vac. The fuse exhibits time-delay characteristics with a typical cold resistance of 0.116O and a typical melting I²t of 62.3 A²·sec, providing reliable protection against transient overcurrents while minimizing nuisance trips. It meets UL standard 248-14 and is RoHS compliant, making it suitable for industrial control circuits, power distribution systems, and consumer electronics requiring coordinated overcurrent protection.
