Why Choose the Mersen J098126 Medium Time-Lag Miniature Fuse?
The Mersen J098126, also identified by the catalogue number MI6SA50V0.63, is a compact medium time-lag semiconductor miniature fuse designed to protect sensitive electronic components and industrial control circuits against overcurrent and short-circuit faults. It forms part of Mersen’s SA range of 6.3 × 32 mm miniature fuse-links.
Its medium time-lag operating characteristic allows the fuse to tolerate brief inrush currents and short-duration electrical surges without unnecessary operation. It still provides dependable protection against sustained overloads and short circuits, helping improve equipment reliability while reducing nuisance fuse replacement.
With a rated current of 0.63 A, a rated voltage of 500 V AC and a 50 kA minimum interrupting rating, the J098126 provides reliable protection for demanding electronic and industrial applications. Its ceramic cartridge body and ferrule terminals enable straightforward clip mounting in compatible fuse holders.
