Overview

The Mersen GSB-V630/1000 miniature fast-acting fuse provides precise overcurrent protection for low-voltage AC circuits. Rated at 250VAC and 0.63A, this 5x20mm glass fuse features axial leads with soldered connections for secure PCB mounting. Designed for fast response, it clears faults within milliseconds to safeguard sensitive electronics in compact industrial and commercial equipment. The glass body allows visual inspection of the fuse element for quick status verification without disassembly. With a 1-1/2" axial lead configuration, it installs directly into fuse holders or PCBs where vibration resistance and electrical integrity are critical. Typical applications include telecommunications equipment, industrial automation systems, power supplies, and consumer electronics. The 0.63A rating makes it ideal for low-power control circuits, instrumentation, and measurement devices. Engineers specify this fuse for space-constrained designs where reliable protection is essential.
