Why Choose the Mersen F090510 MI5SF25V0.315 Miniature Fuse?
The Mersen F090510 (MI5SF25V0.315) is a dependable 5 x 20 mm fast-acting miniature fuse designed to protect electrical distribution circuits, electronic equipment and industrial control systems against overloads and short circuits. As part of the Mersen 5SF IEC miniature fuse series, it provides rapid interruption of excessive current to help protect sensitive components and connected equipment.
This miniature cartridge fuse has a rated current of 0.315 A (315 mA) and a rated voltage of 250 V AC. Its fast-acting operating characteristic responds quickly when current exceeds the permitted level, making it suitable for circuits that do not normally experience significant start-up or inrush currents.
Manufactured in the industry-standard 5 x 20 mm glass cartridge format, the Mersen F090510 can be installed in compatible fuse clips and holders. Its compact construction makes it suitable for industrial machinery, instrumentation, power supplies, electronic assemblies and automation equipment.

Reliable Fast-Acting Circuit Protection
Fast-acting fuses such as the Mersen F090510 are designed to disconnect an electrical circuit rapidly when excessive current occurs. This quick response helps limit thermal and electrical stress on sensitive electronic components, wiring and control equipment.
When the current exceeds the fuse's permitted time-current limits, the internal fuse element melts and interrupts the electrical path. The F090510 is therefore well suited to circuits that require prompt protection and do not experience substantial temporary inrush currents during normal operation.
Typical Applications
- Industrial control panels.
- Electronic equipment and assemblies.
- Instrumentation and test equipment.
- Power supply circuits.
- Automation and process-control systems.
- OEM machinery and commercial electrical equipment.
