Reliable Component Selection for Industrial Systems
Industrial electrical systems depend on components with correctly matched electrical and mechanical characteristics. Products that appear visually similar may have different voltage ratings, current ratings, operating classes, connection types or installation dimensions.
Using the complete Mersen M300138 reference during procurement helps identify the required component, but the reference alone should not replace a full technical compatibility check. All relevant specifications should be confirmed before the product is fitted, particularly when replacing an older component or servicing safety-critical equipment.

- Industrial electrical control panels.
- Power distribution equipment.
- Electrical protection assemblies.
- Manufacturing and production machinery.
- Original equipment manufacturing.
- Electrical maintenance and repair operations.
- Engineering spares and replacement-parts inventories.
