The GMD-1A is a UL-rated 5 x 20mm medium time-delay glass tube fuse designed to protect appliances and consumer electronics from overcurrent conditions. This fuse features a 1 ampere current rating and is part of the GMD series of medium time-delay fuses, which incorporate a coiled wire or thick element wrapped in wire to provide delayed response to temporary current surges. The 5 x 20mm form factor is a standard size used across a wide range of consumer and industrial applications. The time-delay characteristic makes it ideal for circuits with inrush currents or temporary load spikes, while the glass tube construction allows visual inspection of the fuse element. GMD-1A fuses are commonly used in household appliances, consumer electronics, and equipment requiring precise overcurrent protection with tolerance for brief transient currents.
