GMD-2.5A Description

Short technical summary and product information.

The Eaton GMD-2.5A is a 5mm x 20mm glass tube fuse with time-delay (slow blow) characteristics. It is rated for 2.5A at 250V AC and offers a breaking capacity of 100A at 250V AC and 10,000A at 125V AC. This fuse is designed for overcurrent protection in circuits with high inrush currents, such as power supplies and motors.

 

The GMD series features a glass tube with nickel-plated brass endcaps and requires a compatible fuse holder for installation. The time-delay response allows temporary overloads without nuisance tripping. Typical DC cold resistance is 94 mΩ, and maximum voltage drop at rated current is 195 mV.

 

The fuse is UL Listed and CSA Certified under UL/CSA 248-14 standards. It is RoHS3 compliant and available in various packaging options including bulk (100 pcs), poly bag (1000 pcs), and tape on reel (1500 pcs).
