Overview

The Mersen GDL8 is a miniature time-delay fuse designed for precise overcurrent protection in industrial and electronic circuits. Rated at 8A and 250VAC, this fuse features a glass body construction with a 6.3x32mm ferrule size, ensuring compatibility with standard fuse holders. Its time-delay characteristic (I.R. 3) prevents nuisance tripping from temporary inrush currents common in motor starts, power supply turn-on, or capacitive loads. The GDL8 is part of Mersen's GDL series, which includes ampere ratings from 1/16A to 30A and voltage ranges up to 250VAC. This fuse is UL Listed and CSA Certified, meeting U.S. and Canadian safety standards. The glass body allows for visual inspection of the fuse element, enabling quick status verification. With dimensions of 1/4" x 1-1/4", the GDL8 is suitable for protecting sensitive electronic circuits, control panels, and industrial equipment. The ferrule design ensures secure electrical connections, reducing the risk of loose or intermittent contacts. For applications requiring axial leads, the GDL-V8 variant is available with 1-1/2" leads. The GDL series is widely used in power supplies, motor controls, and instrumentation where reliable, time-delayed overcurrent protection is critical.
