The Mersen D300268 is an industrial electrical component identified by the manufacturer reference D300268. It is intended for professional maintenance, repair and OEM replacement applications where this exact Mersen part number is specified in the equipment documentation, approved bill of materials or existing installation.
Matching the complete manufacturer reference is important when maintaining industrial electrical equipment. Selecting the correct component helps reduce compatibility issues, supports efficient maintenance planning and enables purchasing teams to source the specified replacement part accurately.
Detailed electrical ratings and dimensional information for the D300268 could not be reliably verified from publicly available manufacturer information. Before ordering or installation, confirm the product type, current rating, voltage rating, operating class, terminal arrangement and physical dimensions against the original component or an official Mersen datasheet.
Industrial components can share similar housings while having significantly different electrical characteristics, mounting arrangements or operating classes. For this reason, visual similarity alone should not be used to select a replacement. The complete Mersen reference and all marked ratings should be checked before the component is ordered or fitted.
Where the existing label is incomplete or damaged, consult the equipment manufacturer, approved parts list or Mersen technical support. Installing a component with an incorrect current rating, voltage rating, operating characteristic or terminal arrangement could affect equipment protection and performance.

The Mersen D300268 is an industrial electrical component identified by the manufacturer part number D300268. Its exact technical ratings should be confirmed using official Mersen documentation.
Check the complete part number and every marked electrical rating against the original component, equipment manual or approved bill of materials.
No replacement should be selected by appearance alone. Current, voltage, operating class, breaking capacity, dimensions and terminal configuration must all be compatible.
Consult the label on the existing component, the equipment documentation, an official Mersen datasheet or Mersen technical support.
Installation should be completed by a suitably qualified electrical engineer or technician after the equipment has been safely isolated.
Correct manufacturer and part-number identification helps engineers, panel builders and maintenance professionals source compatible components for industrial electrical equipment.
