Overview

The Mersen GSC-V2 Miniature Fuse is a high-performance, time-delay fuse designed for robust circuit protection in demanding industrial environments. Part of Mersen’s trusted GSC-V series, this 5x20mm fuse delivers reliable performance at 250VAC and 2A, making it an ideal choice for applications where transient surges and inrush currents are common. With a time-delay rating, the GSC-V2 provides superior protection against nuisance tripping while ensuring critical equipment remains safeguarded during temporary overloads. Engineered with a glass/ceramic body and axial leads for soldered connections, the GSC-V2 is built to withstand harsh operating conditions, including vibration, temperature fluctuations, and electrical stress. Its compact 5x20mm form factor allows for easy integration into tight spaces, making it a versatile solution for control panels, power supplies, instrumentation, and other compact electrical assemblies. The time-delay characteristic is particularly valuable in applications with motors, transformers, or capacitive loads, where brief current spikes are normal but sustained overloads must be prevented. Mersen, a global leader in electrical protection and thermal management solutions, has designed the GSC-V2 to meet stringent industry standards, ensuring compliance with UL, IEC, and other regulatory requirements. The fuse’s soldered connection design provides a secure, low-resistance interface, reducing the risk of connection failures over time. Whether deployed in industrial automation, renewable energy systems, telecommunications, or consumer electronics, the GSC-V2 delivers consistent performance and long-term reliability. Selecting the right fuse for your application requires careful consideration of voltage ratings, current ratings, and time-delay characteristics. The GSC-V2’s 250VAC rating makes it suitable for low-voltage industrial circuits, while its 2A current rating provides precise protection for sensitive components. Time-delay fuses like the GSC-V2 are preferred in scenarios where momentary overloads are expected, such as during equipment startup or inrush events. Installation is straightforward, with axial leads designed for soldering into PCBs or terminal blocks, ensuring a permanent and stable connection. Mersen’s reputation for innovation and quality is reflected in the GSC-V2, a product that combines durability, precision, and ease of use. Trusted by engineers and technicians worldwide, Mersen’s miniature fuses are a cornerstone of modern electrical protection strategies. For applications where reliability cannot be compromised, the GSC-V2 offers the performance and peace of mind you need. Pair it with Mersen’s comprehensive portfolio of protection solutions to build a robust, future-proof electrical system.
