Mersen N093346 MI5FA40V3.15 high-speed 5 x 20 mm miniature cartridge fuse rated at 3.15 A and 400 V AC for semiconductor and sensitive electronic circuit protection.
£2.68
The Mersen N093346, catalogue number MI5FA40V3.15, is a compact high-speed miniature cartridge fuse designed to protect sensitive semiconductor devices and electronic components against damaging overcurrents and short circuits. Its very fast-acting FA characteristic enables rapid fault interruption, helping to limit the electrical energy passed to protected equipment.
Rated at 3.15 A and 400 V AC, the N093346 is suitable for industrial electronics, automation equipment, power conversion systems and measuring instruments. Its standard 5 × 20 mm cylindrical format enables straightforward installation in compatible clip-mounted fuse holders.
The N093346 combines compact dimensions with a 10 kA minimum breaking capacity and dependable semiconductor protection. Manufactured by Mersen, it provides a reliable solution for OEM equipment, electronic control assemblies and industrial systems where conventional general-purpose fuses may not operate quickly enough.
Semiconductor devices can be damaged by short-duration overcurrent events before a conventional fuse has time to operate. The Mersen N093346 uses a very fast-acting FA characteristic to interrupt fault currents rapidly and reduce the thermal and electrical stress placed on sensitive components.
Its compact cartridge format and high fault-interruption capability make it suitable for electronic equipment where space is restricted and dependable protection is essential. When installed in a correctly rated fuse holder, the N093346 helps improve equipment reliability and reduce the risk of costly component damage.
