£56.44
The Mersen K081843 is a high-performance Protistor® cylindrical fuse-link designed for rapid and dependable protection of sensitive DC electrical circuits. With a rated current of 1.5 A and a voltage rating of 1500 V DC, it is ideally suited to auxiliary circuits, control systems, measuring equipment and monitoring devices.
Part of the Mersen 20 × 127 mm gR range, the K081843 provides fast-acting, full-range protection against overloads and short circuits. Its gR characteristic helps limit fault energy before vulnerable semiconductor components and electronic devices can be damaged.
The fuse features a durable ceramic body, silver-plated copper ferrule terminals and a high DC breaking capacity of 30 kA. These characteristics make the K081843 a reliable choice for industrial automation, renewable energy systems, power conversion equipment and other demanding high-voltage DC applications.
Fast-acting gR fuse-links are designed to interrupt fault currents before damaging thermal and electrical stresses reach sensitive components. This helps protect semiconductor devices, measuring instruments, monitoring equipment and control circuits from costly failure.
The Mersen K081843 combines full-range protection with high fault-clearing capability, making it suitable for systems where reliable performance and rapid interruption are essential. Its cylindrical format also enables straightforward installation in compatible fuse clips and holders.
