Why Choose the Mersen F093293 High-Speed Miniature Fuse?
The Mersen F093293, catalogue reference MI6FA69V2, is a compact high-speed miniature semiconductor fuse designed to provide rapid protection for sensitive semiconductor devices, electronic circuits and industrial control equipment. It forms part of Mersen’s 6.3 × 32 mm FA 690 V fuse series, developed for applications requiring dependable interruption of overcurrents and short circuits.
With a rated current of 2 A and a rated voltage of 690 V AC, the F093293 is suitable for industrial electronics, automation equipment, power conversion systems and semiconductor-based assemblies. Its very fast-acting FA characteristic helps restrict the electrical energy passed during a fault, reducing thermal stress and the risk of damage to valuable electronic components.
The fuse is manufactured in a compact 6.3 × 32 mm cartridge format with ferrule end caps for clip mounting in a compatible fuse holder. This replaceable construction supports convenient installation and maintenance while providing reliable protection in space-restricted electrical and electronic equipment.
