Overview

The Mersen GSA-V3-1/2 (SKU: GSA-V3-1/2) is a time-delay ceramic fuse rated for 250V and 3.5A, designed for critical industrial overcurrent protection. This fuse features a ceramic body for superior thermal management and mechanical strength, making it ideal for harsh environments with temperature fluctuations or vibration. Its time-delay functionality allows it to handle temporary inrush currents common in motor starts or power supply energization without nuisance tripping, while still providing fast response to sustained overloads or short circuits. The compact 1/4" x 1 1/4" size enables installation in space-constrained applications like control panels, power supplies, and industrial equipment. Certified by UL (1/2A–8A, 250VAC) and CSA (1/2A–8A, 250VAC), the GSA-V3-1/2 meets stringent safety standards for reliable performance in manufacturing, automation, telecommunications, and power distribution systems. Choose Mersen for trusted electrical protection backed by decades of innovation.
