Why Choose the Mersen E219194 MI5SM25V8 Miniature Fuse?
The Mersen E219194 (MI5SM25V8) is a dependable 5 x 20 mm medium time-lag miniature fuse designed to protect electrical equipment, distribution circuits and industrial control systems against overloads and short circuits. As part of the Mersen 5SM IEC miniature fuse series, it provides reliable overcurrent protection while tolerating the temporary current surges associated with normal equipment start-up.
This miniature fuse has a rated current of 8 A and a rated voltage of 250 V AC. Its medium time-lag characteristic helps prevent nuisance operation when transformers, power supplies, motors and capacitive loads briefly draw increased current, while still interrupting sustained overloads and fault currents.
Manufactured in the standard 5 x 20 mm glass cartridge format, the Mersen E219194 features nickel-plated brass contact caps and an extinguishing agent for dependable fault interruption. Its compact clip-mounted construction makes it suitable for compatible fuse holders used in industrial machinery, electrical equipment and automation systems.
Key Advantages
- Reliable medium time-lag overcurrent protection.
- 8 A rated current for industrial and electrical equipment.
- 250 V AC rated voltage.
- Tolerates temporary start-up and inrush currents.
- 300 A AC breaking capacity for dependable fault interruption.

Reliable Medium Time-Lag Circuit Protection
Medium time-lag fuses such as the Mersen E219194 are engineered to withstand brief inrush currents that occur when electrical equipment is energised. This characteristic makes the fuse suitable for circuits containing transformers, motors, power supplies and capacitive loads where a fast-acting fuse could operate unnecessarily.
When excessive current continues beyond the permitted time-current limits, the fuse element interrupts the electrical path. Its glass cartridge body, extinguishing agent and 300 A breaking capacity help protect wiring, control components and connected equipment from damage caused by overloads and short circuits.
Typical Applications
- Industrial electrical equipment.
- Electrical distribution circuits.
- Control panels and automation systems.
- Power supplies and transformer circuits.
- Electronic equipment and assemblies.
- OEM machinery and instrumentation.
