Why Choose the Mersen V090546 5ST Miniature Fuse?
The Mersen V090546 is a dependable time-delay glass cartridge fuse designed to protect electrical distribution circuits and industrial equipment against sustained overloads and short circuits. Part of the Mersen 5ST IEC miniature fuse range, it withstands brief inrush currents while providing reliable overcurrent protection.
With a rated current of 2 A and a rated voltage of 250 V AC, the V090546 is suitable for control equipment, power supplies, transformers, small motors and other electrical devices that may draw a temporary surge when energised. Its time-delay characteristic helps reduce nuisance fuse operation during normal equipment start-up.
The fuse uses a standard 5 × 20 mm glass cartridge format, allowing straightforward installation into compatible miniature fuse holders. Its transparent body also enables convenient visual inspection, making it suitable for original equipment installation and routine maintenance applications.
