Overview

The Mersen GSA2 miniature time-delay fuse (SKU: GSA2) provides reliable overcurrent protection for 250VAC systems at a 2A rating. Engineered with a ceramic body for thermal stability and arc suppression, this fuse withstands temporary current surges—such as motor startups—without nuisance tripping while still protecting against sustained overloads and short circuits. Its compact 6.3x32mm ferrule design enables space-efficient installation in electrical panels, control circuits, and auxiliary devices across industrial automation, power distribution, telecommunications, and renewable energy systems. Key specifications include a 250VAC voltage rating, 2A ampere rating, and time-delay characteristic (I.R. The fuse is available in a standard ferrule package for secure terminal connections and is suitable for applications requiring UL Listed and CSA Certified protection for 1/2A through 8A ratings at 250VAC. Additional ratings include 10A, 12A, and 15A at 250VAC, with UL Recognized and CSA Recognized options for broader compatibility. Optional axial lead versions (GSA-V2) provide flexible mounting options for PCB or chassis applications.
