Why Choose the Mersen Q093348 MI5FA40V0.315 High Speed Miniature Fuse?
The Mersen Q093348, catalogue reference MI5FA40V0.315, is a compact high speed semiconductor miniature fuse designed to protect sensitive electronic components against overcurrents and short circuits. As part of Mersen's MI5 FA 400 V miniature fuse range, it provides rapid fault interruption for demanding electronic and industrial applications.
Rated at 0.315 A and 400 V AC, the Q093348 features a very fast-acting FA operating characteristic. This rapid response helps restrict the electrical and thermal energy transferred to semiconductor devices during a fault, reducing the risk of component damage and unplanned equipment downtime.
The fuse uses a compact 5 × 20 mm cylindrical cartridge format designed for clip mounting in a compatible miniature fuse holder. Its very high breaking capacity, low-current rating and space-saving construction make it suitable for industrial electronics, instrumentation, power supplies, automation equipment and semiconductor protection circuits.
