Why Choose the Mersen E210339 MI5HT25V16 Miniature Fuse?
The Mersen E210339 (MI5HT25V16) is a high-performance 5 x 20 mm time-delay miniature fuse designed to protect electrical equipment, motors and industrial circuits against overloads and short circuits. As part of the Mersen 5HT IEC miniature fuse series, it combines compact dimensions with dependable high breaking capacity protection.
This fuse has a rated current of 16 A and a rated voltage of 250 V AC. Its time-delay characteristic enables it to withstand brief, high start-up currents without unnecessary operation, making it particularly suitable for motor circuits and equipment with substantial inrush current.
Manufactured in the standard 5 x 20 mm cartridge format, the Mersen E210339 offers a breaking capacity of 1,500 A. It is suitable for installation in compatible fuse holders used within industrial machinery, power supplies, control panels and electrical distribution equipment.

Reliable Time-Delay Protection for High-Inrush Loads
Time-delay fuses such as the Mersen E210339 are engineered to tolerate temporary current surges that occur when motors, transformers and other inductive equipment are energised. This helps prevent nuisance fuse operation during normal start-up while maintaining reliable protection against sustained overloads.
When excessive current continues beyond the permitted time-current limits, the fuse element safely interrupts the circuit. Its 1,500 A breaking capacity helps contain significant fault currents and protect connected equipment, wiring and control components.
Typical Applications
- Motor protection circuits.
- Industrial electrical equipment.
- Machinery control panels.
- Power supplies and transformers.
- Electrical distribution circuits.
- Automation systems and OEM equipment.
