Eaton Drive Shaft Extension for Dumeco DMV 250N and 400N Switch-Disconnectors 10 x 245mm

The Eaton drive shaft extension is a precision-engineered component specifically designed for seamless integration with Dumeco DMV 250N and 400N switch-disconnectors. Measuring 10mm in profile and 245mm in length, this shaft extension provides the necessary reach to connect the switch mechanism to the external operating handle, ensuring reliable and safe mechanical operation within electrical distribution panels and switchgear assemblies.

Advantages

This drive shaft extension offers exceptional durability and structural integrity, which are critical for maintaining consistent performance in demanding industrial environments. By facilitating the correct alignment between the switch-disconnector and the control handle, it ensures smooth operation and reduces mechanical stress on the internal components. Its robust construction guarantees long-term reliability, making it an essential accessory for professional electrical installations where precision and safety are paramount.

Suitable for

• Industrial power distribution systems
• Commercial electrical switchgear panels
• Retrofitting or extending switch-disconnector controls
• Applications requiring remote operation of DMV 250N and 400N switches

When it may not be suitable

This component is specifically engineered for the Dumeco DMV 250N and 400N series and is not compatible with other switch-disconnector models or different shaft profiles. It should not be used in applications where the required distance between the switch and the handle exceeds the 245mm length provided by this extension.

Key specifications

• Profile size: 10mm
• Length: 245mm
• Compatibility: Dumeco DMV 250N and 400N switch-disconnectors
• Material: High-strength industrial grade metal

How to use

To install the drive shaft extension, ensure that the power supply to the switchgear is completely disconnected. Insert the shaft into the designated coupling on the switch-disconnector mechanism, ensuring it is fully seated and aligned. Attach the operating handle to the other end of the shaft, verifying that the rotation of the handle correctly engages the switch mechanism. Test the operation manually before re-energizing the system to ensure smooth movement and proper switching action.

What to consider before purchase

• Verify the exact model of your switch-disconnector to ensure compatibility with the DMV 250N or 400N series.
• Measure the required distance between the switch and the mounting surface to confirm that the 245mm length is sufficient.
• Ensure that the 10mm profile matches your existing handle coupling mechanism.

Usage recommendations

Always perform installation according to local electrical safety standards and manufacturer guidelines. Regularly inspect the shaft connection during routine maintenance to ensure no loosening has occurred due to vibration or mechanical wear.
