CHM2D Equivalent & Substitute Parts

Part Overview

The CHM2D is a cartridge fuse holder manufactured by Eaton - Bussmann Electrical Division, designed for 690V applications with a 32A current rating. This DIN rail-mounted holder accommodates 5AG midget fuses (10mm x 38mm) and features a 2-circuit configuration with screw terminal connections.

The CHM2D is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement and maintenance applications where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CHM2D is determined by the following critical parameters:

• Mechanical Compatibility: Mounting type (DIN Rail), fuse size (10mm x 38mm), and circuit count (2) must remain constant
• Electrical Compatibility: Voltage and current ratings must meet or exceed the original specification
• Connector Type: Screw terminal termination must be maintained
• Fuse Type: Cartridge fuse accommodation (5AG midget) must be preserved

The CHM2D CHM2DU substitute maintains identical mechanical form factor and connector type. However, the substitute operates at reduced voltage (600V) and current (30A) ratings compared to the original specification.

Parameter Comparison

Engineering Selection Recommendations

The CHM2DU serves as an active substitute for the obsolete CHM2D. Both components share identical mechanical and connector specifications, enabling direct physical installation in existing DIN rail assemblies.

The CHM2DU operates at reduced electrical ratings (600V / 30A versus 690V / 32A). Selection of the CHM2DU is appropriate for applications where the system voltage and current requirements do not exceed 600V and 30A respectively.

The CHM2DU carries RoHS compliance certification, whereas compliance status for the CHM2D is not specified. For applications subject to RoHS regulatory requirements, the CHM2DU provides documented compliance.

Frequently Asked Questions (FAQ)

Q: Can the CHM2DU be used as a direct replacement for the CHM2D?

A: The CHM2DU provides mechanical and connector compatibility with the CHM2D. However, the reduced voltage (600V) and current (30A) ratings must be verified against system requirements before substitution.

Q: What are the key differences between CHM2D and CHM2DU?

A: The primary differences are voltage rating (690V versus 600V) and current rating (32A versus 30A). Both components maintain identical fuse size, circuit count, mounting type, and termination style.

Q: Are both parts compatible with 5AG midget fuses?

A: Yes. Both the CHM2D and CHM2DU accommodate 5AG cartridge fuses with dimensions 0.394" Dia x 1.496" L (10mm x 38mm).

Q: What is the significance of the CHM2DU being RoHS compliant?

A: RoHS compliance indicates the CHM2DU meets restrictions on hazardous substances. This certification is relevant for applications subject to RoHS regulatory frameworks. The CHM2D compliance status is not specified in available documentation.

Q: Can the CHM2DU be installed in the same DIN rail assembly as the CHM2D?

A: Yes. Both components feature identical DIN rail mounting specifications and screw terminal connections, enabling installation in the same mechanical assembly.
