Overview

The Mersen GGA3/4 miniature fuse (SKU: GGA3/4) is a time-delay, 5x20mm ferrule fuse rated at 250VAC and 0.75A. Designed for reliable overcurrent protection in low-voltage power supplies, control circuits, and consumer electronics, this fuse combines a glass body for visual status indication with a time-delay characteristic to handle temporary inrush currents while rapidly interrupting dangerous overloads and short circuits. Its compact 5x20mm size ensures compatibility with standard fuse holders and equipment designs, making it ideal for integration into power distribution units, instrumentation, and specialized electronic assemblies. The GGA3/4 meets stringent safety standards with UL Listing and CSA Certification, providing confidence in its performance and reliability. With a 250VAC voltage rating and precise 0.75A current rating, this fuse is particularly well-suited for circuits with inductive loads, such as motors, where momentary current surges occur during startup. Engineered for long-term performance, the GGA3/4 delivers dependable protection to safeguard sensitive components and maintain system integrity.
