Mersen X089467 FD20GC150V2 Protistor high-speed cylindrical gR fuse-link rated at 2 A and 1500 V DC for semiconductor and high-voltage DC circuit protection.
£117.31
The Mersen X089467, catalogue reference FD20GC150V2, is a high-speed cylindrical fuse-link designed to provide dependable protection for sensitive semiconductor equipment and high-voltage DC circuits. Part of the Mersen Protistor® 20 × 190 mm gR fuse range, it combines fast fault interruption with full-range overcurrent protection.
This fuse is specifically engineered for demanding DC applications where rapid isolation of short-circuit and overload conditions is essential. Its low-current 2 A rating makes it particularly suitable for auxiliary circuits, control systems, monitoring equipment and semiconductor-based power conversion assemblies.
With a rated operating voltage of 1500 V DC and a durable ceramic cylindrical body, the X089467 provides reliable electrical and thermal performance in industrial environments. Its ferrule-style terminals allow secure installation in compatible fuse clips and holders used within power electronics, railway equipment and industrial control panels.
High-speed gR fuse-links are designed to interrupt electrical faults rapidly before excessive thermal or electrical energy can damage semiconductor devices. This makes the Mersen X089467 suitable for equipment containing sensitive power electronic components that require faster protection than conventional industrial fuses can provide.
The fuse’s 1500 V DC rating supports use in modern high-voltage power conversion, transportation and industrial systems. Its full-range gR characteristic provides protection against both overload currents and high-level short circuits, helping improve equipment reliability and reduce unplanned downtime.
