Eaton Drive Shaft Extension for Dumeco DMV 250N and 400N Switch-Disconnectors 10 x 135mm

The Eaton drive shaft extension is a precision-engineered component designed specifically for seamless integration with Dumeco DMV 250N and 400N switch-disconnectors. Measuring 10 x 135 mm, this shaft extension facilitates the correct positioning of the operating handle within electrical distribution panels, ensuring that the switch-disconnector can be operated safely and effectively from the exterior of the enclosure. It is built to maintain high mechanical integrity, providing a stable connection between the handle and the switching mechanism in demanding industrial environments.

Advantages

This extension offers a robust mechanical coupling that ensures consistent performance and reliability for power control systems. By allowing for flexible handle placement, it simplifies the layout of complex electrical panels and improves accessibility for maintenance personnel. The high-quality construction ensures durability under frequent operation, maintaining the safety standards required for industrial switch-disconnector applications.

Suitable for

• Electrical distribution panels
• Industrial power control systems
• Switch-disconnector installations requiring extended handle reach

When it may not be suitable

This component is exclusively designed for use with Eaton Dumeco DMV 250N and 400N models. It is not compatible with other switch-disconnector series or different shaft dimensions. Attempting to use this extension with incompatible equipment may result in mechanical failure or unsafe operation.

Key specifications

• Dimensions: 10 x 135 mm
• Compatibility: Dumeco DMV 250N and 400N switch-disconnectors
• Function: Mechanical drive shaft extension

How to use

To install the drive shaft extension, ensure that the power supply to the distribution panel is completely disconnected. Insert the extension into the designated coupling point on the switch-disconnector mechanism. Secure the connection according to the manufacturer's installation guidelines for the DMV series. Once attached, verify that the operating handle is correctly aligned and that the switch engages and disengages smoothly without any binding or resistance.

What to consider before purchase

• Verify the specific model of your switch-disconnector to ensure it is a DMV 250N or 400N.
• Measure the required distance between the switch and the panel door to confirm that the 135 mm length is sufficient.
• Ensure that the installation environment meets the technical requirements for industrial electrical components.

Usage recommendations

Always perform a functional test after installation to ensure the handle operates the switch-disconnector correctly before energizing the system. Regularly inspect the mechanical coupling during scheduled maintenance to ensure no loosening has occurred due to vibration.
