CHM2DI Equivalent & Substitute Parts

Part Overview

The CHM2DI is a 2-circuit cartridge fuse holder designed for DIN rail mounting, rated for 32 A at 690V with 10mm x 38mm (0.394" Dia x 1.496" L) fuse accommodation. This component is classified as obsolete, making identification of suitable alternatives essential for ongoing maintenance and system upgrades. The CHM2DI accepts 5AG midget fuses and features screw terminal connections for secure installation in industrial electrical distribution systems.

Key Parameters

Substitute Part Grouping Explanation

The CHM2DIU is identified as a direct substitute for the CHM2DI based on the following alignment criteria:

Matching Parameters:

• Identical fuse size accommodation: 10mm x 38mm (5AG midget)
• Identical number of circuits: 2
• Identical mounting type: DIN Rail
• Identical fuse holder type: Cartridge
• Identical manufacturer: Eaton - Bussmann Electrical Division
• Same series family: CHM

Differing Parameters:

• Current rating: 30 A (CHM2DIU) versus 32 A (CHM2DI)
• Voltage rating: 600V (CHM2DIU) versus 690V (CHM2DI)
• Product status: Active (CHM2DIU) versus Obsolete (CHM2DI)

The CHM2DIU operates within lower electrical parameters than the CHM2DI, making it suitable for applications where the full 32 A / 690V capability is not required.

Parameter Comparison

Engineering Selection Recommendations

The CHM2DIU is an active product offering from the same manufacturer, providing continuity of supply for the obsolete CHM2DI. Selection of the CHM2DIU is appropriate when system requirements permit operation at 30 A / 600V. The CHM2DIU maintains mechanical and electrical compatibility through identical fuse accommodation (10mm x 38mm), circuit count (2), and mounting configuration (DIN Rail).

The CHM2DIU carries RoHS Compliance certification, whereas the CHM2DI status is not specified. Both parts maintain REACH Unaffected and EAR99 ECCN classifications, ensuring consistent regulatory standing.

For applications requiring the full 32 A / 690V rating of the original CHM2DI, alternative solutions from the Eaton - Bussmann Electrical Division CH or CHM series should be evaluated to ensure electrical parameter requirements are met.

Frequently Asked Questions (FAQ)

Q: Can the CHM2DIU directly replace the CHM2DI in all applications?

A: The CHM2DIU is mechanically compatible and accepts the same fuse type and size. However, it is rated for 30 A at 600V, compared to the CHM2DI's 32 A at 690V. Substitution is valid only when the application operates within these lower electrical parameters.

Q: What is the significance of the different voltage ratings?

A: The CHM2DI is rated for 690V operation, while the CHM2DIU is rated for 600V. The voltage rating indicates the maximum voltage the fuse holder can safely isolate and interrupt. Selection must match or exceed the system voltage.

Q: Are the fuse cartridges interchangeable between these two models?

A: Yes. Both the CHM2DI and CHM2DIU accommodate 5AG midget fuses with dimensions of 10mm x 38mm. Fuse cartridge compatibility is maintained across both models.

Q: Why is the CHM2DI listed as obsolete?

A: Product obsolescence indicates that the manufacturer has discontinued production. The CHM2DIU represents the active alternative within the Eaton - Bussmann product line.

Q: What is the difference in packaging between these parts?

A: The CHM2DI packaging is listed as standard, while the CHM2DIU is supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance.

Q: Are both parts RoHS compliant?

A: The CHM2DIU is confirmed RoHS Compliant. The CHM2DI RoHS status is not specified in the provided data.
