Overview

The Mersen GSC8 miniature time-delay fuse (SKU: GSC8) delivers precise overcurrent protection for sensitive electronic circuits. Rated at 125 VAC and 8 A, this 5x20mm fuse features a glass/ceramic body with ferrule connections, ensuring compatibility with standard fuse holders. Its time-delay characteristic allows temporary inrush currents—such as those from motor startups or power supply surges—without nuisance tripping, while still providing robust protection against sustained overcurrents and short circuits. Designed for industrial control panels, power supplies, consumer electronics, medical devices, and telecommunications equipment, the GSC8 meets UL and CSA safety standards for 4A through 8A at 125VAC. The fuse’s compact 5x20mm size makes it ideal for space-constrained applications, and its ferrule design ensures secure electrical contact. With a 10kA interrupting rating (I.R.) at 125VAC, the GSC8 provides reliable performance in high-fault-current environments. Mersen’s trusted reputation in electrical protection guarantees consistent quality and compliance with global standards.
