The reference Mersen F300086 could not be matched confidently to a current Mersen product page, manufacturer datasheet or authoritative distributor catalogue. Whilst the reference format is consistent with Mersen Protistor® semiconductor fuse part numbers, no verified technical information is available for F300086 from publicly available manufacturer sources.
The supplied reference may represent a discontinued product, a regional catalogue number, a legacy item number or an incomplete manufacturer reference. Before specifying or replacing this component, the complete catalogue number should be confirmed from the fuse body, original packaging or equipment documentation.
Key Advantages of Accurate Product Identification
Ensures the correct electrical protection device is selected.
Prevents installation of an incompatible fuse.
Confirms voltage, current and utilisation category.
Helps verify dimensions and mounting style.
Supports compliance with manufacturer recommendations.
Reduces the risk of equipment damage and unnecessary downtime.
Identification Details Required
Complete Mersen catalogue number.
Series or product family.
Rated current.
Rated voltage.
Fuse utilisation category (gG, aR, gR, etc.).
Terminal or blade configuration.
Body size.
Photographs of all product markings.
Selecting the Correct Mersen Fuse
Industrial semiconductor fuses and low-voltage protection devices must always be selected using verified manufacturer specifications. Using an incorrect current rating, voltage rating or mounting configuration may compromise equipment protection and system safety.
Once the complete Mersen catalogue number has been identified, the appropriate datasheet should be consulted to verify electrical characteristics, dimensions, interrupting capacity and installation requirements.
Possible Applications
Industrial power distribution.
Variable speed drives.
Power converters.
Motor control equipment.
Renewable energy systems.
Industrial switchgear.
Semiconductor protection systems.

Frequently Asked Questions
What is the Mersen F300086?
The supplied reference could not be matched to a verified Mersen product listing or manufacturer datasheet.
Is F300086 a complete part number?
It may be a legacy, regional or incomplete reference. Additional markings on the product should be checked to confirm the full catalogue number.
Why are the technical specifications unavailable?
No authoritative manufacturer documentation could be located that positively identifies the F300086 reference.
Can I replace it with a similar Mersen fuse?
No. Any replacement should only be selected after confirming the current rating, voltage rating, fuse class, dimensions and terminal configuration.
How can I identify the correct replacement?
Check the complete markings on the fuse body or packaging, including the catalogue number, electrical ratings and series designation.
Trusted Industrial Circuit Protection
Correct product identification ensures industrial electrical systems receive the appropriate level of protection while maintaining equipment reliability, compliance and operational safety.
