Overview

The Mersen GGA-V4/10 miniature time-delay fuse is a high-performance, glass-body fuse designed for precision protection in industrial and electronic applications. Rated at 250VAC and 0.4A, this 5x20mm fuse combines reliable overcurrent protection with time-delay characteristics, making it ideal for circuits where temporary surges or inrush currents are common. The soldered connection ensures secure, low-resistance terminations, reducing the risk of intermittent failures or overheating in demanding environments. As part of Mersen’s industry-leading fuse portfolio, the GGA-V4/10 is engineered to meet stringent safety standards while delivering consistent performance across a wide range of operating conditions. This fuse is particularly well-suited for applications where transient overloads must be tolerated without nuisance tripping, such as in power supplies, motor controllers, transformers, and instrumentation systems. Its time-delay feature allows it to withstand brief current spikes—common in inductive loads—while still providing robust protection against sustained overcurrents. The 5x20mm glass body offers excellent visibility for inspection and is compatible with standard fuse holders, simplifying both installation and maintenance. Whether used in control panels, test equipment, or telecommunications infrastructure, the GGA-V4/10 ensures reliable circuit protection with minimal downtime. Mersen, a global leader in electrical protection solutions, has designed the GGA-V4/10 to meet the rigorous demands of modern industrial applications. With a reputation for durability and precision, Mersen fuses are trusted by engineers and technicians worldwide to safeguard critical systems. The time-delay functionality of this fuse makes it an excellent choice for applications where momentary current surges are expected, such as during equipment startup or in circuits with capacitive loads. Additionally, its compact 5x20mm form factor allows for flexible integration into space-constrained designs without compromising performance. For professionals specifying fuses, the GGA-V4/10 offers a balance of safety, reliability, and ease of use. Its 250VAC rating makes it suitable for both low- and medium-voltage applications, while the 0.4A current rating provides targeted protection for sensitive components. The soldered axial leads ensure a secure connection, reducing the risk of vibration-induced failures in high-shock environments. When combined with Mersen’s commitment to quality and compliance with international standards, the GGA-V4/10 becomes an indispensable component in any protection strategy. Installation is straightforward, requiring only a compatible fuse holder or panel mount. The fuse’s glass body allows for quick visual confirmation of its status, and its time-delay characteristic ensures that brief overloads do not trigger unnecessary interruptions. Whether deployed in industrial automation, renewable energy systems, or consumer electronics, the Mersen GGA-V4/10 delivers the performance and peace of mind that professionals demand. For circuits where precision protection is non-negotiable, this miniature time-delay fuse stands as a trusted solution.
