## Summary description

This Eaton drive shaft extension is designed for use with Dumeco DMV 250N and 400N switch-disconnectors. Measuring 10 x 400 mm, this accessory allows for flexible installation of the operating handle when the switch is mounted deeper within an electrical enclosure. It ensures reliable mechanical coupling and safe operation of the switch-disconnector system in industrial power distribution applications.

## Long description

The Eaton drive shaft extension is a precision-engineered accessory designed specifically for integration with Dumeco DMV 250N and 400N switch-disconnectors. This component serves as a critical link in industrial power distribution systems, enabling the mechanical operation of a switch-disconnector mounted deep within an electrical enclosure. By extending the reach of the operating handle, it provides the necessary flexibility for panel builders and electrical engineers to design enclosures that meet specific spatial requirements while maintaining safe and reliable switching capabilities.
Advantages
This drive shaft extension offers robust mechanical coupling, ensuring that the torque from the external handle is transferred accurately to the switch-disconnector mechanism. Its durable construction is designed to withstand the rigors of industrial environments, providing consistent performance over the lifespan of the electrical installation. The 10 x 400 mm dimensions allow for significant depth adjustment, making it an essential component for complex switchgear configurations where standard shaft lengths are insufficient.
Suitable for
Industrial power distribution panels
Deep-mounted switch-disconnector installations
Custom electrical enclosure configurations
Upgrading or retrofitting existing DMV 250N and 400N systems
When it may not be suitable
This extension is exclusively compatible with Eaton Dumeco DMV 250N and 400N switch-disconnectors. It is not suitable for use with other switch series or different mechanical coupling standards. Furthermore, it should not be used in applications where the required shaft length exceeds the physical dimensions provided or where the mechanical load exceeds the design specifications of the shaft.
Key specifications
Compatibility: Eaton Dumeco DMV 250N and 400N switch-disconnectors
Shaft dimensions: 10 x 400 mm
Material: Industrial-grade metal
Function: Mechanical drive extension for operating handles
How to use
Installation involves inserting the drive shaft extension into the designated coupling point on the switch-disconnector mechanism. Ensure that the shaft is securely locked into place according to the specific mounting instructions provided with the DMV switch-disconnector. The operating handle is then attached to the external end of the shaft. It is essential to verify that the alignment is precise to prevent mechanical stress or binding during operation. Always ensure the power is disconnected before performing any installation or maintenance on the switchgear.
What to consider before purchase
Verify the exact model of your switch-disconnector to ensure compatibility
Measure the required depth within your enclosure to confirm the 400 mm length is sufficient
Ensure the shaft profile matches the handle and switch coupling requirements
Usage recommendations
Always follow the manufacturer's installation manual for the specific switch-disconnector model. Regularly inspect the mechanical coupling for signs of wear or misalignment during routine maintenance cycles to ensure continued safe operation.
