MM1-B-14-620-A-2AB-B-J Circuit Breaker Equivalent & Substitute Parts

Part Overview

The MM1-B-14-620-A-2AB-B-J is a single-pole magnetic hydraulic delay circuit breaker manufactured by Carling Technologies, rated for 20A at 250V AC and 80V DC with lever panel mount actuation. This component is classified as Active product status and holds multiple regulatory approvals including CCC, TUV, and UL489A certification. Substitute parts become necessary when the primary manufacturer part is unavailable, when supply chain optimization is required, or when equivalent performance specifications can be met through alternative manufacturers while maintaining identical electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MM1-B-14-620-A-2AB-B-J is determined by strict equivalence across the following parameters: current rating of 20A, AC voltage rating of 250V, DC voltage rating of 80V, magnetic hydraulic delay breaker type, single-pole configuration, lever actuator, and panel mount installation method. All identified substitute parts maintain identical values across these critical parameters. Substitutes are grouped by manufacturer (Sensata-Airpax) and series designation (IEG, IEL, IUG), with each part meeting the same functional and electrical requirements as the primary component.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical equivalence to the MM1-B-14-620-A-2AB-B-J. Selection among substitutes should be based on the following factors:

Regulatory Compliance: The primary part holds CCC, TUV, and UL489A approvals. Substitute parts IEG1-1-63-20.0-01-V and IEG6-1-72-20.0-01-V carry CSA, TUV, and UL1077 certifications. IEL1-1-51-20.0-01-V carries no specified approval agencies in the provided data. IELK1-1-72-20.0-01-V holds UL1077 certification. IUG1-1-62-30.0-CQ-01 carries no specified approval agencies in the provided data. Applications requiring specific regulatory compliance should reference the approval agency requirements of the target system.

Inventory Availability: IELK1-1-72-20.0-01-V offers the highest inventory level at 1212 pieces. IEG1-1-63-20.0-01-V provides 1051 pieces, and IUG1-1-62-30.0-CQ-01 provides 1095 pieces. IEL1-1-51-20.0-01-V provides 919 pieces.

RoHS Compliance: All substitute parts are RoHS Compliant. The primary part is ROHS3 Compliant. Both designations satisfy RoHS requirements.

Moisture Sensitivity Level: All Sensata-Airpax substitute parts specify MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can IEG1-1-63-20.0-01-V be used as a direct replacement for MM1-B-14-620-A-2AB-B-J?

A: Yes. Both parts share identical electrical ratings (20A, 250V AC, 80V DC), breaker type (magnetic hydraulic delay), mounting configuration (panel mount), actuator type (lever), and pole count (1). Physical form factor compatibility must be verified through mechanical drawings specific to the application.

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

A: Both IEG and IEL series parts meet all electrical and mechanical parameters of the primary part. The series designation reflects internal design architecture and manufacturing lineage from Sensata-Airpax. Functional performance is equivalent across all specified parameters.

Q: Are there packaging differences between substitute parts?

A: The primary part specifies packaging as "-" (not provided). 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 packaged in Bulk. IUG1-1-62-30.0-CQ-01 specifies packaging as "-" (not provided). Packaging requirements should be confirmed with procurement specifications.

Q: Which substitute part has the best regulatory coverage?

A: IEG1-1-63-20.0-01-V and IEG6-1-72-20.0-01-V both carry CSA, TUV, and UL1077 certifications. The primary part carries CCC, TUV, and UL489A certifications. Regulatory requirements vary by application and geographic region; system-level compliance must be verified.

Q: Can I mix substitute parts from different series in the same application?

A: All substitute parts meet identical electrical and mechanical specifications. However, design consistency and supply chain management typically favor standardization on a single part number within a given application or system revision.

Q: What is the significance of the MSL rating on substitute parts?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. These parts can be stored and handled without special environmental controls related to moisture exposure, simplifying logistics and inventory management.
