CHM2I Equivalent & Substitute Parts

Part Overview

The CHM2I is a cartridge fuse holder manufactured by Eaton - Bussmann Electrical Division, designed for 690V applications with a 32A current rating and 2-circuit configuration on DIN rail mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and component sourcing in industrial electrical installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CHM2I is determined by the following critical parameters that must align across candidate parts:

• Mounting Configuration: DIN rail mounting required
• Fuse Cartridge Compatibility: 10mm x 38mm (5AG Midget) cartridge acceptance
• Circuit Count: 2-circuit configuration
• Termination Interface: Screw terminal connection
• Voltage Class: Minimum 600V rating (CHM2I operates at 690V)
• Current Capacity: Minimum 30A rating (CHM2I rated at 32A)

The LPSM0002ZXID from Littelfuse Inc. meets these substitution criteria with compatible mechanical and electrical parameters, though with a 600V voltage rating and 30A current specification.

Engineering Selection Recommendations

The LPSM0002ZXID serves as a functional equivalent for the obsolete CHM2I based on mechanical and electrical compatibility. Key considerations for component selection:

• Active Product Status: The LPSM0002ZXID is actively manufactured and supported, providing supply chain continuity for the discontinued CHM2I.
• Voltage Derating: The LPSM0002ZXID operates at 600V versus the CHM2I's 690V rating. System voltage must not exceed 600V for this substitute to be applied.
• Current Derating: The LPSM0002ZXID is rated at 30A versus the CHM2I's 32A. Circuit current must not exceed 30A for this substitute to be applied.
• Mechanical Compatibility: Both holders accept identical 10mm x 38mm cartridge fuses with 2-circuit configuration and screw terminal termination.
• Regulatory Compliance: Both parts maintain REACH Unaffected status. The LPSM0002ZXID additionally carries ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the LPSM0002ZXID directly replace the CHM2I in all applications?

A: Direct replacement is limited by voltage and current derating. The LPSM0002ZXID operates at 600V maximum and 30A maximum, compared to the CHM2I's 690V and 32A ratings. Substitution is valid only when system voltage does not exceed 600V and circuit current does not exceed 30A.

Q: Are the cartridge fuses interchangeable between these two holders?

A: Yes. Both the CHM2I and LPSM0002ZXID accept 5AG Midget cartridge fuses with 10mm x 38mm dimensions. Fuse cartridge compatibility is maintained across both holders.

Q: What is the difference between screw terminal and pressure plate termination?

A: The LPSM0002ZXID offers dual termination options (screw terminal and pressure plate), while the CHM2I uses screw terminal only. Both termination methods provide electrical connection; pressure plate termination offers an alternative connection interface on the Littelfuse model.

Q: Is the LPSM0002ZXID suitable for 690V applications?

A: No. The LPSM0002ZXID is rated for 600V maximum. For 690V applications, alternative components rated at or above 690V must be sourced.

Q: What packaging is available for the LPSM0002ZXID?

A: The LPSM0002ZXID is supplied in box packaging. Verify packaging requirements for your procurement specifications.
