Why Choose the Mersen Y084408 Miniature Semiconductor Fuse?

The Mersen Y084408 is a compact and dependable 6.3 × 32 mm miniature semiconductor fuse designed to protect sensitive electronic components and control equipment against overcurrent faults. Also identified by catalogue number MI6SA25V2.5, it has a rated current of 2.5 A and a rated voltage of 250 V AC.

Part of the Mersen SA miniature semiconductor fuse series, the Y084408 features a medium time-lag characteristic that allows it to tolerate brief inrush and transient currents without unnecessary operation. It still provides reliable interruption when a sustained overload or short circuit threatens the protected circuit.

The fuse is manufactured with a ceramic insulating body and ferrule terminals for clip mounting in compatible fuse holders. Its compact format, very high breaking capacity and controlled time-current response make it suitable for industrial electronics, power supplies, control apparatus and OEM equipment.
