The GMD-1.5A is a 5 mm × 20 mm time-delay glass tube fuse designed for low breaking capacity circuit protection. It features a rated current of 1.5A at 250V with an interrupting rating of 100A at rated voltage (50Hz), and is constructed with nickel-plated brass endcaps. The fuse exhibits a cold resistance of 0.158O, a typical melting I²t of 25 amps²·s, and a typical voltage drop of 240 mV at rated current. It is UL listed, CSA certified, and PSE/JET approved, meeting UL/CSA 248-14 standards. This fuse is ideal for protecting sensitive electronic circuits and equipment requiring reliable time-delay protection with minimal voltage drop.
