Overview

Mersen W219761 cylindrical fuse-link gG (Size 10x38) is a high-reliability protection component designed for low-voltage electrical distribution circuits and industrial applications. Rated at 500VAC and 12A, this fuse-link provides robust overcurrent and short-circuit protection for cables, motors, and LV networks. The ceramic body ensures thermal stability and mechanical strength, while silver-plated contacts deliver low-resistance electrical connections for consistent performance. With a rated breaking capacity of 120kA, the W219761 safely interrupts fault currents up to this limit, protecting downstream equipment from dynamic effects of high short-circuit currents. The 10x38mm cylindrical design is a standard IEC size, compatible with a wide range of fuse holders and systems. Ideal for applications requiring precise current protection in industrial, commercial, and utility installations where reliability and compliance with IEC standards are critical.
