Mersen SMG Series Fast-Acting Glass Cartridge Fuse
The Mersen SMG Series is a fast-acting glass cartridge fuse family built for 250VAC circuit protection, with the broader family rated across 125-350 VAC and 140 VDC. Housed in a 4.5mm x 14.5mm (2AG) cylindrical non-rejection glass body, these fuses cover an ampere range of 1/10-10 A and are designed for clip mounting into standard fuse holders. Nickel plated brass contact materials support reliable conductivity, and SMG-V lead-style versions add a 1-1/2" wire lead on each end for direct-wire installations. Backed by UL and CSA recognition, the SMG Series is a dependable choice for protecting electronic circuits and equipment.
