MERSEN FUSE 250V FA 20 A 6.32 P MI6FA25V20P

Why Choose the Mersen L098105 High Speed Semiconductor Fuse?

The Mersen L098105 is a compact high speed semiconductor miniature fuse designed to protect sensitive electronic components, semiconductor devices and measuring or control apparatus against damaging overcurrent and short-circuit conditions. Part of the Mersen MI6FA miniature fuse series, it features a very fast-acting FA characteristic that helps minimise the electrical and thermal energy transferred to protected equipment.

This fuse combines rapid fault interruption with a compact cylindrical construction, making it suitable for industrial electronics, power conversion systems and automation equipment. Its very high breaking capacity supports dependable protection in circuits where conventional general-purpose fuses may not respond quickly enough to prevent semiconductor damage.

With a rated current of 20 A, a rated voltage of 250 V AC and a compact 6.3 × 32 mm body, the Mersen L098105 provides substantial current capacity without requiring significant installation space. Its clip-mounted construction and integrated striker support straightforward installation and rapid identification when the fuse has operated.
