Why Choose the Mersen Q206071 5ST Miniature Fuse?

The Mersen Q206071, also identified by the catalogue reference MI5ST25V10, is a compact 5 x 20 mm time-delay cartridge fuse designed to protect electrical distribution circuits, industrial controls and electronic equipment against overloads and short circuits. As part of the established Mersen 5ST IEC miniature fuse series, it can withstand brief start-up currents while responding reliably to sustained overcurrent conditions.

The Q206071 features a transparent glass cartridge body that allows straightforward visual inspection of the internal fuse element. Its standard cylindrical dimensions provide compatibility with suitable 5 x 20 mm fuse holders and mounting clips, making it practical for original equipment manufacture, panel construction and routine maintenance replacement.

With a rated current of 10 A and a rated voltage of 250 V AC, this miniature fuse is suitable for circuits containing motors, transformers, power supplies and other equipment that may draw a temporary surge when energised.
