MERSEN FUSE 250V FA 5 A 6.32 S084311

Why Choose the Mersen S084311 High-Speed Miniature Fuse?

The Mersen S084311 is a compact and dependable high-speed miniature fuse designed to protect sensitive electronic components, semiconductor devices and measuring or control equipment against damaging overcurrents and short circuits. As part of the Mersen MI6 FA 125V–250V series, it provides very fast fault interruption for demanding industrial and electronic applications.

With a rated current of 5 A and an IEC rated voltage of 250 V AC, the S084311 helps minimise the electrical and thermal energy passed to protected components during a fault. Its very fast-acting FA characteristic makes it particularly suitable for semiconductor circuits that require quicker protection than conventional general-purpose fuses can provide.

The fuse features a compact 6.3 × 32 mm cartridge format and is intended for clip mounting in a compatible fuse holder. Its high breaking capacity, robust construction and space-saving dimensions make it suitable for power electronics, instrumentation, automation systems and industrial control equipment.
