Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MM2-B-20-620-3-3JB-B-C are qualified based on the following critical parameters that must match identically:

Mandatory Matching Parameters:

• Current Rating: 20A
• Voltage Rating - AC: 250V
• Voltage Rating - DC: 80V
• Breaker Type: Magnetic (Hydraulic Delay)
• Mounting Type: Panel Mount
• Actuator Type: Lever
• Number of Poles: 2
• Illumination: None

All identified substitute parts meet these electrical and mechanical specifications. Substitution is valid when all parameters listed above are identical between the main part and the substitute part. Differences in manufacturer, series designation, or packaging do not affect functional interchangeability when core parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can any of these substitute parts replace the MM2-B-20-620-3-3JB-B-C directly?

A: Yes. All listed substitute parts are parametric equivalents with identical electrical ratings (20A, 250V AC, 80V DC), breaker type (Magnetic Hydraulic Delay), mounting configuration (Panel Mount), actuator type (Lever), and pole count (2). Direct substitution is valid based on these matching specifications.

Q: What is the difference between the substitute parts?

A: The substitute parts differ by manufacturer series designation (IEG, IEGH, IEGS, IEL, IUG), approval agency certifications, and packaging format. All electrical and mechanical parameters remain identical. Selection should be based on certification requirements for the specific application and inventory availability.

Q: Does packaging format affect interchangeability?

A: Packaging format (Bulk or other designations) does not affect functional interchangeability. Packaging relates only to order quantity and handling, not to electrical or mechanical performance.

Q: Which substitute part has the broadest approval coverage?

A: IEGH11-1-72-20.0-01-V and IEGS66-1-61-20.0-A-41-V both carry CSA, TUV, and UL1077 approvals, providing the most comprehensive certification coverage among the listed substitutes.

Q: Are all substitute parts currently in stock?

A: Yes. All substitute parts are listed as New Original In Stock with quantities ranging from 736 to 903 units.

Q: What approval agencies are critical for my application?

A: Approval agency requirements depend on the end-use application and regional regulations. The original part carries CCC, CSA, and UL1077 certifications. Substitute parts carry varying certification profiles. Select a substitute with certifications matching or exceeding your application requirements.
