Suitable for

• Industrial control panels
• Commercial power distribution systems
• HVAC equipment protection
• Motor control circuits
• General electrical infrastructure maintenance

This fuse holder may not be suitable for applications requiring high-speed fuse operation or specific environmental protections not covered by its standard rating. It is not intended for use in high-voltage systems exceeding 600V or in environments with extreme moisture or corrosive gases without additional protective enclosures.

Key specifications

• Number of poles: 3
• Maximum current rating: 30A
• Maximum voltage rating: 600V
• Mounting type: DIN-rail
• Fuse type: Cylindrical

To use the Eaton CHM3DU, snap the unit onto a standard DIN-rail within your electrical enclosure. Insert the appropriate cylindrical fuses into the holders, ensuring they are seated correctly. Once the fuses are installed, close the modular housing to secure the connection. The unit allows for easy access to fuses, enabling quick replacement when necessary without the need for specialized tools.

What to consider before purchase

• Verify that the fuse dimensions match the cylindrical standard supported by this holder.
• Ensure the electrical system voltage and current requirements do not exceed the 600V/30A rating.
• Check available space on the DIN-rail within your control cabinet.
• Confirm that the environmental conditions of the installation site are appropriate for this component.

Usage recommendations: Always ensure the power supply is disconnected before installing or replacing fuses to prevent electrical shock. Regularly inspect the fuse holder for signs of wear or heat damage to maintain optimal system safety and performance.
