MERSEN FUSE 250V FA 0,25 A 6.32 250V FA 0.25A 6X32

Why Choose the Mersen H084302 High-Speed Miniature Fuse?

The Mersen H084302, catalogue reference MI6FA25V0.25, is a compact very fast-acting miniature semiconductor fuse designed to protect sensitive electronic components, semiconductor devices and measuring or control equipment against damaging overcurrents and short circuits. It forms part of Mersen's proven 6.3 × 32 mm FA fuse range.

Rated at 0.25 A and 250 V AC, the H084302 provides rapid fault interruption to limit the thermal and electrical energy reaching vulnerable components. Its high-speed operating characteristic makes it particularly suitable for circuits where conventional general-purpose fuses may not respond quickly enough to protect sensitive semiconductor devices.

The fuse features a durable ceramic cylindrical body and is designed for clip mounting in a compatible fuse holder. Its compact dimensions and very high breaking capacity make it suitable for industrial controls, power electronics, instrumentation and OEM equipment requiring dependable circuit protection.
