Why Choose the Mersen F084415 Medium Time-Lag Miniature Fuse?
The Mersen F084415, catalogue reference MI6SA25V12.5, is a compact medium time-lag semiconductor protection fuse designed to protect sensitive electronic components, semiconductor devices and control equipment against damaging overcurrents. It forms part of Mersen’s 6.3 × 32 mm SA miniature fuse series, developed for circuits that experience brief start-up or inrush currents during normal operation.
With a rated current of 12.5 A and a rated voltage of 250 V AC, the F084415 provides dependable protection for industrial electronics, power supplies, control apparatus and other electrical equipment. Its medium time-lag SA characteristic allows short-duration current surges to pass without unnecessary fuse operation while responding reliably to sustained overloads and short circuits.
The fuse is manufactured in a durable 6.3 × 32 mm ceramic cartridge format with ferrule end caps for clip mounting in a compatible fuse holder. Its compact dimensions, high breaking capacity and replaceable design make it suitable for industrial equipment where reliable protection and convenient maintenance are required.
