Why Choose the Mersen A215602 Medium Time-Lag Glass Cartridge Fuse?
The Mersen A215602, catalogue reference MI5SM25V2, is a compact and dependable medium time-lag miniature cartridge fuse designed to protect electrical distribution circuits, industrial equipment and electronic systems against sustained overloads and short-circuit faults. As part of the Mersen 5SM IEC miniature fuse series, it provides a balanced response to temporary current surges and prolonged overcurrent conditions.
Rated at 2 A and 250 V AC, the A215602 can tolerate brief increases in current that may occur when equipment is energised, while still interrupting persistent faults. Its medium time-lag characteristic helps reduce nuisance operation in circuits that experience moderate start-up currents.
The fuse features a standard 5 × 20 mm glass body and is designed for installation in compatible fuse clips and miniature fuse holders. Its compact cylindrical construction makes it suitable for industrial control equipment, power supplies, instrumentation, electrical distribution circuits and OEM electronic assemblies.
