Specifications

The GMA-1A is rated for a current of 1 Ampere and a voltage of 250V AC or DC. It is a fast-acting fuse, meaning it will blow quickly when the current exceeds its rating, typically within milliseconds. The fuse is constructed with a glass tube, allowing for visual inspection to determine if it has blown. The end caps are typically made of nickel-plated brass or similar conductive material. The interrupting rating is typically 35A or higher, depending on the voltage. The physical dimensions are standardized for glass cartridge fuses. It is commonly used in low to medium energy circuits where the risk of overload needs to be mitigated. It is UL listed, meaning it has been tested and certified to meet safety standards.

The GMA-1A's fast-acting characteristic provides rapid protection against overcurrents, preventing damage to sensitive electronic components. The glass cartridge allows for easy visual inspection, simplifying troubleshooting. The 1 Ampere current rating makes it suitable for a wide range of applications. Its compliance with safety standards ensures reliable and safe operation. Because of the glass cartridge design it can be easily inspected to visually determine if it has blown and needs replacement.
