Why Choose the Mersen P087022 Medium Time-Lag Semiconductor Fuse?
The Mersen P087022, catalogue reference MI5SA25V3.15, is a compact 5 × 20 mm semiconductor miniature fuse designed to protect sensitive electronic components, semiconductor devices and industrial control apparatus against damaging overcurrents. Its medium time-lag SA operating characteristic accommodates brief current surges while maintaining reliable protection against sustained overloads and short circuits.
Rated at 3.15 A and 250 V AC, the P087022 is suitable for electronic circuits and control systems where temporary inrush currents may occur during normal start-up. Its controlled response helps reduce nuisance fuse operation while ensuring that genuine electrical faults are safely interrupted.
The standard 5 × 20 mm clip-mounted format supports straightforward installation in compatible miniature fuse holders. Its compact construction, surge tolerance and dependable operating performance make the Mersen P087022 a practical choice for OEM machinery, automation equipment, instrumentation and electronic assemblies.
