Why Choose the Mersen X093170 High-Speed Miniature Fuse?
The Mersen X093170, catalogue number MI6FA40V10P, is a compact and dependable high-speed semiconductor protection fuse designed to protect sensitive electronic components against damaging overcurrents and short circuits. It forms part of Mersen’s 6.3 × 32 mm FA miniature fuse range for power electronic, control and industrial automation applications.
Its very fast-acting FA characteristic helps minimise the electrical and thermal energy transferred to vulnerable semiconductor devices during a fault. This makes the X093170 suitable for protecting diodes, thyristors, converters, rectifiers and associated electronic circuitry where a conventional general-purpose fuse may not operate quickly enough.
Rated at 10 A and 400 V AC, the Mersen X093170 combines a robust ceramic cartridge body with a high 150 kA minimum interrupting rating. Its integrated striker provides a clear indication when the fuse has operated, while its ferrule terminals and clip-mounted format support straightforward installation in compatible fuse holders.

Fast Protection with Integrated Fuse Indication
Semiconductor devices can be damaged by high fault currents within a very short period. High-speed fuses such as the Mersen X093170 are designed to interrupt these faults rapidly and restrict the energy passed into the protected circuit, helping prevent costly damage to sensitive power electronic components.
The integrated striker provides a practical visual or mechanical indication when the fuse has operated, helping maintenance teams identify faults more efficiently. Its ceramic body, high interrupting capacity and compact cartridge design make it suitable for control panels, converters, power supplies and industrial automation equipment.
Typical Applications
- Semiconductor converters and power electronic equipment.
- Diode, thyristor and rectifier protection.
- Industrial control and automation systems.
- Electronic power supplies and converters.
- Measurement and instrumentation equipment.
- Fuse monitoring systems using striker indication.
