MM1-B-14-630-A-2AB-B-J Circuit Breaker Equivalent & Substitute Parts

Part Overview

The MM1-B-14-630-A-2AB-B-J is a single-pole, lever-actuated circuit breaker manufactured by Carling Technologies, rated for 30A at 250V AC and 80V DC. The device employs magnetic hydraulic delay technology for overcurrent protection in panel-mount applications. This part maintains active product status with 772 units in current inventory stock.

Equivalent and substitute parts become necessary when the primary manufacturer part is unavailable, when supply chain constraints occur, or when design flexibility permits selection from qualified alternative manufacturers. All substitute parts listed maintain identical electrical and mechanical parameters required for direct functional replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MM1-B-14-630-A-2AB-B-J is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

• Current Rating: 30A (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)

Critical Mechanical Parameters:

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

Non-Functional Parameters:

• Illumination: None (exact match required)

All four substitute parts listed—CEG1-1-51-30.0-91-V, CEGF6-1-52-30.0-01-V, IEG6-1-72-30.0-91-V, and IELK1-1-72-30.0-91-V—satisfy these criteria and are therefore qualified as parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain active product status and full compliance with applicable regulatory frameworks. Selection among these equivalents should be based on the following factors:

Approval Agency Alignment: The MM1-B-14-630-A-2AB-B-J carries CCC, TUV, and UL489A certifications. CEG1-1-51-30.0-91-V holds UL489A certification. CEGF6-1-52-30.0-01-V holds UL489A certification. IEG6-1-72-30.0-91-V carries CSA, TUV, and UL1077 certifications. IELK1-1-72-30.0-91-V carries UL1077 certification. Applications requiring specific certification alignment should reference the approval agency requirements of the end-use system.

Environmental Compliance: All substitute parts are RoHS compliant and classified under identical ECCN and HTSUS codes as the primary part. The MM1-B-14-630-A-2AB-B-J is ROHS3 compliant and REACH unaffected. Substitute parts CEG1-1-51-30.0-91-V, CEGF6-1-52-30.0-01-V, and IEG6-1-72-30.0-91-V are REACH unaffected. IELK1-1-72-30.0-91-V does not specify REACH status in provided data.

Packaging and Inventory Availability: CEGF6-1-52-30.0-01-V offers the highest current inventory at 1037 units. CEG1-1-51-30.0-91-V provides 903 units. IELK1-1-72-30.0-91-V provides 868 units. IEG6-1-72-30.0-91-V provides 683 units. Packaging for all substitute parts is specified as bulk.

Frequently Asked Questions (FAQ)

Q: Can CEG1-1-51-30.0-91-V directly replace MM1-B-14-630-A-2AB-B-J in all applications?

A: CEG1-1-51-30.0-91-V is a parametric equivalent with identical electrical and mechanical specifications. Direct replacement is supported for applications where UL489A certification satisfies system requirements. Applications requiring CCC or TUV certification should verify that system-level approvals accommodate UL489A certification alone.

Q: What is the difference between CEGF6-1-52-30.0-01-V and IEG6-1-72-30.0-91-V?

A: Both parts are parametric equivalents with identical electrical and mechanical parameters. CEGF6-1-52-30.0-01-V carries UL489A certification and is manufactured by Sensata-Airpax. IEG6-1-72-30.0-91-V carries CSA, TUV, and UL1077 certifications and is also manufactured by Sensata-Airpax. Selection depends on certification requirements of the application.

Q: Are all substitute parts available in the same packaging as the original MM1-B-14-630-A-2AB-B-J?

A: The original part packaging is specified as "-" (not provided in input data). All substitute parts are available in bulk packaging. Packaging compatibility should be confirmed against specific procurement requirements.

Q: Do all substitute parts meet RoHS compliance requirements?

A: All four substitute parts are RoHS compliant. The original MM1-B-14-630-A-2AB-B-J is ROHS3 compliant. For applications requiring ROHS3 compliance specifically, CEG1-1-51-30.0-91-V, CEGF6-1-52-30.0-01-V, and IEG6-1-72-30.0-91-V are specified as RoHS compliant without ROHS3 designation in provided data. IELK1-1-72-30.0-91-V is specified as RoHS compliant without ROHS3 designation.

Q: Which substitute part has the best inventory availability?

A: CEGF6-1-52-30.0-01-V maintains the highest inventory level at 1037 units in stock.

Q: Are there any electrical performance differences between the substitute parts?

A: All substitute parts are parametric equivalents with identical current ratings (30A), voltage ratings (250V AC / 80V DC), breaker type (Magnetic Hydraulic Delay), pole configuration (1), actuator type (Lever), and mounting type (Panel Mount). No electrical performance differences exist among the listed equivalents.

Q: What is the REACH status of IELK1-1-72-30.0-91-V?

A: REACH status for IELK1-1-72-30.0-91-V is not specified in the provided technical data. The original MM1-B-14-630-A-2AB-B-J is REACH unaffected. Confirmation of REACH compliance should be obtained from the manufacturer for applications subject to REACH regulations.
