Why Choose the Mersen A078890 Miniature Fuse?
The Mersen A078890, manufacturer designation MI6FA50V0.063, is a compact very fast-acting miniature fuse designed to protect sensitive electrical and electronic equipment against damaging overcurrent and short-circuit conditions. Its rapid operating characteristic helps limit the energy passed into vulnerable components when a fault occurs.
Part of Mersen’s MI6FA range of high-rupturing-capacity miniature fuses, the A078890 combines a standard 6.3 × 32 mm cylindrical format with a rated voltage of 500 V AC. This compact construction makes it suitable for installation in compatible fuse holders used within control equipment, instrumentation and electronic assemblies.
With a low nominal current rating of 0.063 A, equivalent to 63 mA, the Mersen A078890 is intended for circuits requiring highly sensitive protection. Its very fast-acting FA characteristic makes it particularly useful where fault current must be interrupted quickly to protect delicate components and low-current control circuits.

Rapid Protection for Sensitive Electrical Circuits
Very fast-acting fuses are designed to interrupt excessive current with minimal delay. This rapid response helps reduce thermal and electrical stress on sensitive circuit components that may be damaged before a standard or time-delay fuse operates.
The Mersen A078890 is particularly suited to low-current equipment requiring a precisely rated protective device. Its standard cylindrical dimensions allow straightforward replacement in a correctly rated 6.3 × 32 mm fuse holder, while its 500 V AC rating supports a broad range of control and electronic applications.
Typical Applications
- Electronic control circuits.
- Industrial instrumentation and monitoring equipment.
- Power supply input and output protection.
- Laboratory and test equipment.
- Measurement and sensing devices.
- Automation and process control systems.
