The Mersen A300495 is identified by the manufacturer reference A300495. This unique part number can help engineers, maintenance personnel and procurement teams distinguish the required component when sourcing a replacement for compatible industrial electrical equipment.
Accurate identification is important when replacing electrical components because products with a similar appearance may have different current ratings, voltage ratings, operating characteristics, dimensions or connection arrangements. The complete part number and every marking on the original component should be checked before ordering.
Product-specific technical information for the Mersen A300495 could not be verified through publicly searchable manufacturer or distributor sources. Its precise product type, catalogue designation and electrical specifications should therefore be confirmed using the original component label, equipment bill of materials or documentation supplied by Mersen.
Replacement electrical components should be selected using their full technical specification rather than physical appearance alone. Current rating, voltage rating, operating characteristic, interrupting capacity, dimensions and terminal arrangement can all determine whether a component is suitable for a particular application.
Before installing the Mersen A300495, compare the complete reference and every technical marking with the existing component, equipment manual, wiring diagrams and bill of materials. Where information is incomplete, confirmation should be obtained from Mersen or a suitably qualified technical supplier.

A300495 is a manufacturer-specific Mersen component reference. Its precise product type and technical ratings should be confirmed from the original component label or official Mersen documentation.
It should only be treated as a direct replacement after the complete part number, electrical ratings, operating characteristics, dimensions and connection arrangement have been confirmed against the original component.
Product-specific voltage and current ratings could not be verified through publicly searchable sources. Check the original component markings, equipment documentation or information supplied directly by Mersen.
Compare the complete Mersen reference and all technical markings with the existing component, equipment bill of materials, electrical drawings and manufacturer documentation.
Any electrical installation or replacement work should be completed by a suitably qualified professional in accordance with the equipment documentation, applicable regulations and site safety procedures.
Confirming the full technical specification before ordering helps reduce replacement errors, equipment downtime and the risk of installing an incompatible component.
