The manufacturer part number Mersen A087331 could not be matched confidently to a current official Mersen product page or technical datasheet. To prevent inaccurate specifications from being published, electrical ratings, fuse classification, dimensions, breaking capacity, I²t values, power dissipation and EAN information have not been estimated.
Please verify the complete catalogue reference printed alongside A087331 on the fuse, packaging, quotation or Mersen datasheet before using this product in an electrical installation. Mersen catalogue references commonly include additional characters that identify the fuse size, utilisation category, voltage, current rating and terminal arrangement.
A fuse must be selected according to its complete manufacturer designation and confirmed electrical characteristics. Before installation, check the rated current, rated voltage, AC or DC system type, utilisation category, breaking capacity, fuse dimensions, terminal configuration and compatibility with the intended fuse holder.
Do not substitute another Mersen fuse solely because it has a similar physical appearance or part number. An incorrectly specified fuse may fail to provide the required overload, short-circuit or semiconductor protection.
Tick the specs you need, then view products that match.

A087331 appears to be a Mersen manufacturer part number, but its complete product designation and technical specifications could not be verified from an official current product record.
No. The rated current and voltage should be confirmed using the full catalogue reference or an official Mersen datasheet.
No. A replacement must match the required current, voltage, utilisation category, breaking capacity, dimensions and terminal arrangement.
It may be printed on the fuse body, end label, packaging, purchase documentation or the original Mersen technical datasheet.
Always confirm the complete Mersen catalogue reference and official technical data before specifying or installing a fuse in safety-critical electrical equipment.
