Why Choose the Mersen A095450 MI5SA40V0.315 Miniature Fuse?
The Mersen A095450 MI5SA40V0.315 is a compact semiconductor miniature fuse designed to protect sensitive electronic components and control circuits against damaging overcurrents and short circuits. Part of Mersen’s MI5SA 400 V fuse series, it combines dependable circuit protection with a space-saving 5 × 20 mm cartridge format.
Its medium time-lag SA operating characteristic allows the fuse to tolerate brief inrush and transient currents without unnecessary operation. At the same time, it responds effectively to sustained overloads and fault currents, making it suitable for electronic equipment, power supplies and industrial control circuits that experience temporary current surges during normal operation.
Rated at 0.315 A and 400 V AC, the Mersen A095450 is designed for clip mounting in a compatible fuse holder. Its ceramic body, nickel-plated brass end caps and high breaking capacity provide reliable performance in demanding industrial and electronic applications.

Reliable Protection for Sensitive Electronic Circuits
Electronic components can be vulnerable to overcurrents that generate excessive heat and cause permanent damage. The Mersen A095450 helps protect sensitive circuits by interrupting sustained overloads and short-circuit currents before damaging energy reaches connected equipment.
Its medium time-lag characteristic is particularly useful in circuits that experience harmless transient or start-up currents. This reduces nuisance fuse operation while maintaining dependable protection against genuine electrical faults.
Typical Applications
- Semiconductor device protection.
- Industrial electronic control equipment.
- Power supplies and control transformers.
- Automation and instrumentation circuits.
- Circuits with inrush or transient current conditions.
- OEM electronic and electrical equipment.
