Why Choose the Mersen A089493 FD20GB100V10T High-Speed Fuse?

The Mersen A089493, catalogue number FD20GB100V10T, is a high-speed Protistor® cylindrical fuse link designed specifically for protecting sensitive equipment in high-voltage DC applications. Its fast-acting, full-range gR characteristic provides effective protection against both overloads and short-circuit currents.

Rated at 10 A and 1000 V DC, the A089493 is particularly suitable for auxiliary circuits, control systems and measuring or monitoring devices used in industrial power conversion equipment. Its current-limiting performance helps reduce the fault energy transferred to connected components, supporting reliable operation and minimising equipment damage.

The fuse features a compact 20 × 127 mm cylindrical body with ferrule terminals for installation in compatible fuse clips. An integrated striker provides remote or mechanical fuse-status indication, while its high 100 kA DC breaking capacity enables dependable fault interruption in demanding industrial systems.
