MERSEN FUSE 400V FA 6,3 A 6.32 P MI6FA40V6.3P

Why Choose the Mersen C080916 Semiconductor Miniature Fuse?

The Mersen C080916, catalogue number MI6FA40V6.3P, is a high-speed semiconductor miniature fuse designed to protect sensitive electronic components and power semiconductor devices against damaging overcurrents and short circuits. As part of Mersen's 6.3 × 32 mm FA/FB 400 V miniature fuse series, it delivers rapid fault interruption for demanding industrial and electronic applications.

With a rated current of 6.3 A and a rated voltage of 400 V AC, the C080916 is engineered for circuits where semiconductor components require faster protection than conventional general-purpose fuses can provide. Its high-speed FA operating characteristic helps restrict the thermal energy transferred during a fault, reducing the risk of damage to valuable equipment.

The fuse features a compact ceramic body, ferrule terminals and a built-in striker indication system that provides a clear mechanical indication when the fuse has operated. Its clip-mounted design enables straightforward installation in compatible 6.3 × 32 mm fuse holders used in power supplies, converters, industrial controls and electronic assemblies.
