Why Choose the Mersen G089476 Protistor® High-Speed Fuse?
The Mersen G089476 is a high-performance Protistor® cylindrical semiconductor fuse designed to protect sensitive power electronic components in demanding high-voltage DC systems. Rated at 32 A and 1500 V DC, it provides rapid fault interruption to help minimise thermal and electrical damage to semiconductor devices during short-circuit conditions.
Part of the Mersen Protistor® 20 × 190 mm gR (gRC) series, the G089476 delivers low I²t performance, reduced power losses and dependable operation at elevated temperatures. These characteristics make it especially suitable for modern DC equipment where conventional circuit protection may not respond quickly enough to safeguard valuable semiconductor components.
Developed for high-performance protection in railway power and auxiliary circuits, this IEC high-speed fuse is also suitable for industrial converters, rectifiers and other critical DC power systems. Its cylindrical format supports straightforward installation in compatible fuse holders within electrical cabinets and power conversion equipment.
