Why Choose the Mersen M300138 Industrial Electrical Component?

The Mersen M300138 is a professional industrial electrical component identified by the manufacturer reference M300138. It is intended for use with correctly matched Mersen electrical protection, power distribution or control equipment in maintenance, replacement and original equipment applications.

Accurate component selection is essential for maintaining electrical system reliability and reducing the risk of fitting an incompatible replacement. Ordering by the complete Mersen M300138 reference helps maintenance engineers, panel builders and procurement teams manage replacement parts and engineering inventories more effectively.

Before ordering or installation, the product type, voltage rating, current rating, operating characteristics, connection arrangement, dimensions and mounting configuration should be verified against the original component, equipment documentation or current Mersen technical information.

  • Manufactured by Mersen, a specialist in electrical power management and protection.
  • Clearly identified by manufacturer reference M300138.
  • Suitable for professional maintenance, replacement and OEM requirements.
  • Supports accurate purchasing and engineering stock management.
  • Designed for use with correctly matched industrial electrical equipment.
  • Suitable for demanding professional electrical environments.

Key Features

  • Mersen industrial electrical product.
  • M300138 manufacturer part number.
  • Intended for compatible electrical protection and distribution systems.
  • Suitable for professional electrical engineering applications.

  • Manufacturer-specific identification helps reduce ordering errors.
  • Suitable for panel-building, machinery and OEM applications.

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.

Typical Applications

  • Industrial electrical control panels.
  • Power distribution equipment.
  • Electrical protection assemblies.
  • Manufacturing and production machinery.
  • Original equipment manufacturing.
  • Electrical maintenance and repair operations.
