Why Choose the Mersen A084410 MI6SA25V4 Miniature Fuse?
The Mersen A084410 MI6SA25V4 is a compact 4 A semiconductor miniature fuse designed to provide reliable overcurrent and short-circuit protection for sensitive electronic components, control equipment and industrial circuits. Part of Mersen’s MI6SA miniature fuse series, it combines a space-saving 6.3 × 32 mm format with a high interrupting capability.
Its medium time-lag SA operating characteristic allows the fuse to withstand brief inrush and transient currents without unnecessary operation, while still responding effectively to sustained overloads and fault conditions. This makes it particularly suitable for electronic equipment and circuits where temporary current surges occur during start-up or normal operation.
Rated at 4 A and 250 V AC, the Mersen A084410 is designed for clip mounting in a compatible fuse holder. Its ceramic body, nickel-plated brass end caps and very high breaking capacity provide dependable performance in demanding industrial and electronic applications.

Reliable Protection for Sensitive Electronic Circuits
Semiconductor miniature fuses are designed to protect electronic components and control apparatus from damaging overcurrents. The medium time-lag behaviour of the Mersen A084410 allows normal transient or start-up currents to pass while interrupting sustained overloads and short-circuit currents.
Its compact dimensions make it suitable for printed circuit equipment, power supplies, control modules and other applications where installation space is limited. The high breaking capacity helps ensure safe fault interruption, even when substantial prospective short-circuit currents are present.
Typical Applications
- Semiconductor device protection.
- Electronic control equipment.
- Industrial power supplies.
- Automation and control circuits.
- Instrumentation and test equipment.
- Circuits with inrush or transient current conditions.
