Why Choose the Mersen W085372 5HT Miniature Fuse?
The Mersen W085372 is a dependable time-delay ceramic miniature cartridge fuse designed to protect electrical distribution circuits, motors and industrial equipment against overloads and short circuits. Part of the Mersen 5HT IEC miniature fuse series, it combines effective fault protection with the ability to withstand brief, high inrush currents during normal equipment start-up.
With a rated current of 1 A and a rated voltage of 250 V AC, the W085372 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 while maintaining reliable protection against sustained overcurrent conditions.
The fuse features a standard 5 × 20 mm ceramic cartridge construction and a high 1,500 A breaking capacity. Its compact dimensions allow straightforward installation into compatible fuse clips and miniature fuse holders used throughout industrial control panels and OEM electrical equipment.
