Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MM1-B-30-620-1-1AB-B-C are qualified based on the following critical parameters that must match exactly:

• 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: 1
• Illumination: None

All identified substitute parts are manufactured by Sensata-Airpax and maintain identical electrical and mechanical specifications. These parts are classified as parametric equivalents, meaning they perform the same circuit protection function within the same electrical operating envelope and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and full compliance with applicable regulatory standards. The MM1-B-30-620-1-1AB-B-C carries CCC, CSA, and UL1077 approvals. Substitute parts from Sensata-Airpax carry CSA, TUV, and UL1077 certifications (IEG1-1-63-20.0-01-V and IEG6-1-72-20.0-01-V), UL1077 certification (IELK1-1-72-20.0-01-V), or no specific agency listing noted (IEL1-1-51-20.0-01-V and IUG1-1-62-30.0-CQ-01). All substitute parts are RoHS compliant and REACH unaffected. Selection should be based on certification requirements specific to the end application and regulatory jurisdiction.

Frequently Asked Questions (FAQ)

Q: Can IEG1-1-63-20.0-01-V be used as a direct replacement for MM1-B-30-620-1-1AB-B-C?

A: Yes. Both parts share identical electrical ratings (20A, 250V AC, 80V DC), breaker type (Magnetic Hydraulic Delay), mounting configuration (Panel Mount), and actuator type (Lever). Both are single-pole devices with no illumination. Functional interchangeability is confirmed across all critical parameters.

Q: What is the difference between the IEG and IEL series substitutes?

A: Both IEG and IEL series parts meet all electrical and mechanical specifications for substitution. The difference lies in series designation and internal design architecture. All listed parts maintain identical external performance characteristics and mounting compatibility.

Q: Are there packaging differences between the main part and substitutes?

A: The main part MM1-B-30-620-1-1AB-B-C is specified with packaging designation "-". Substitute parts IEG1-1-63-20.0-01-V, IEG6-1-72-20.0-01-V, IEL1-1-51-20.0-01-V, and IELK1-1-72-20.0-01-V are supplied in Bulk packaging. IUG1-1-62-30.0-CQ-01 is specified with packaging designation "-". Packaging differences do not affect functional compatibility.

Q: Do all substitutes carry the same regulatory certifications?

A: No. The main part carries CCC, CSA, and UL1077 approvals. IEG series parts carry CSA, TUV, and UL1077 certifications. IEL1-1-51-20.0-01-V carries no specific agency listing in the provided data. IELK1-1-72-20.0-01-V carries UL1077 certification. IUG1-1-62-30.0-CQ-01 carries no specific agency listing in the provided data. Certification requirements must be verified against application-specific regulatory mandates.
