Key Parameters

Substitute Part Grouping Explanation

Substitution of the MM1-B-62-620-1-2CB-B-C is determined by equivalence across the following critical parameters:

Electrical Parameters:

• Current Rating: 20A (exact match required)
• Voltage Rating - AC: 250V (exact match required)
• Voltage Rating - DC: 80V (exact match required)
• Breaker Type: Magnetic (Hydraulic Delay) (exact match required)

Mechanical Parameters:

• Mounting Type: Panel Mount (exact match required)
• Actuator Type: Lever (exact match required)
• Number of Poles: 1 (exact match required)

Functional Parameters:

• Illumination: None (exact match required)

All substitute parts listed below satisfy these parameters without deviation. Substitution is based on functional equivalence and does not require design modification or application re-qualification.

Engineering Selection Recommendations

All substitute parts listed maintain active product status and satisfy the electrical and mechanical requirements of the MM1-B-62-620-1-2CB-B-C. Selection among substitute options is based on the following factors:

Regulatory Compliance:

• MM1-B-62-620-1-2CB-B-C carries CCC, CSA, and UL1077 approvals
• IEG1-1-63-20.0-01-V carries CSA, TUV, and UL1077 approvals
• IEG6-1-72-20.0-01-V carries CSA, TUV, and UL1077 approvals
• IEL1-1-51-20.0-01-V carries no specified approval agencies
• IELK1-1-72-20.0-01-V carries UL1077 approval
• IUG1-1-62-30.0-CQ-01 carries no specified approval agencies

Applications requiring CSA certification should prioritize IEG1-1-63-20.0-01-V or IEG6-1-72-20.0-01-V. Applications requiring CCC certification should retain the original MM1-B-62-620-1-2CB-B-C.

Environmental Compliance: All substitute parts are RoHS compliant. The original part is ROHS3 compliant. IEG6-1-72-20.0-01-V and the original part both specify REACH Unaffected status.

Inventory Availability: IELK1-1-72-20.0-01-V maintains the highest inventory level at 1212 units. IEL1-1-51-20.0-01-V maintains the lowest inventory level at 919 units.

Frequently Asked Questions (FAQ)

Q: What determines whether a circuit breaker can substitute for the MM1-B-62-620-1-2CB-B-C?

A: Substitution requires exact equivalence across eight critical parameters: breaker type (magnetic hydraulic delay), current rating (20A), AC voltage rating (250V), DC voltage rating (80V), mounting type (panel mount), actuator type (lever), number of poles (1), and illumination status (none). All listed substitute parts satisfy these requirements.

Q: Are the Sensata-Airpax substitute parts mechanically compatible with existing panel cutouts designed for the MM1-B-62-620-1-2CB-B-C?

A: All substitute parts share identical mounting type (panel mount) and actuator type (lever) specifications. Mechanical compatibility with existing panel installations is determined by dimensional specifications not provided in this reference. Physical verification is required before installation.

Q: Do all substitute parts carry the same regulatory approvals as the original MM1-B-62-620-1-2CB-B-C?

A: No. The original part carries CCC, CSA, and UL1077 approvals. Substitute parts carry different approval combinations. IEG1-1-63-20.0-01-V and IEG6-1-72-20.0-01-V carry CSA and TUV approvals in addition to UL1077. IEL1-1-51-20.0-01-V and IUG1-1-62-30.0-CQ-01 carry no specified approval agencies. IELK1-1-72-20.0-01-V carries UL1077 approval only. Application regulatory requirements determine which substitute is appropriate.

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

A: Both IEL and IEG series parts satisfy all electrical and mechanical parameters. The IEG series (IEG1-1-63-20.0-01-V and IEG6-1-72-20.0-01-V) carries CSA and TUV approvals. The IEL series (IEL1-1-51-20.0-01-V and IELK1-1-72-20.0-01-V) carries limited or no specified approvals. Series selection is determined by regulatory requirements and approval agency mandates.

Q: Can the IUG1-1-62-30.0-CQ-01 be used as a direct replacement?

A: The IUG1-1-62-30.0-01-CQ satisfies all electrical and mechanical parameters. However, no approval agencies are specified for this part. Applications requiring specific regulatory certifications should confirm approval status before selection.

Q: What packaging formats are available for substitute parts?

A: The original MM1-B-62-620-1-2CB-B-C is supplied in unspecified packaging. Sensata-Airpax substitute parts are supplied in bulk packaging, with the exception of IUG1-1-62-30.0-CQ-01, which is supplied in unspecified packaging.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts are RoHS compliant. The original part is ROHS3 compliant, which represents a higher compliance standard. Applications with ROHS3 requirements should retain the original part.
