MM1-B-14-630-A-2AB-B-N Circuit Breaker Equivalent & Substitute Parts
Part Overview
The MM1-B-14-630-A-2AB-B-N is a single-pole, magnetic hydraulic delay circuit breaker manufactured by Carling Technologies. This panel-mount breaker is rated for 30A at 250V AC and 80V DC operation with lever actuation. The product maintains active status with full compliance to CCC, TUV, and UL approval standards. Substitute parts are identified when inventory constraints, lead time requirements, or supply chain disruptions necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Engineering Selection Recommendations
All three substitute parts are functionally equivalent to the MM1-B-14-630-A-2AB-B-N and maintain active product status. Selection among substitutes is determined by approval agency requirements and compliance certifications:
MM1-B-14-630-A-2AB-B-N (Primary): Approved under CCC, TUV, and UL standards. Select when CCC certification is a mandatory requirement.
CEGF6-1-52-30.0-01-V: Approved under UL489A. Select when UL489A certification satisfies system requirements and CCC is not mandated.
IEG6-1-72-30.0-91-V: Approved under CSA, TUV, and UL1077. Select when CSA or UL1077 certification is required and CCC is not mandated.
IELK1-1-72-30.0-91-V: Approved under UL1077. Select when UL1077 certification is the applicable standard and CCC is not mandated.
All substitute parts are RoHS compliant and REACH unaffected. Moisture sensitivity level for all substitutes is MSL 1 (Unlimited). ECCN and HTSUS classifications are identical across all parts.
Frequently Asked Questions (FAQ)
Q: Can CEGF6-1-52-30.0-01-V replace MM1-B-14-630-A-2AB-B-N in all applications?
A: CEGF6-1-52-30.0-01-V is electrically and mechanically equivalent. Substitution is valid when UL489A certification meets system requirements. If CCC certification is mandatory, the original MM1-B-14-630-A-2AB-B-N must be used.
Q: What is the difference between IEG6-1-72-30.0-91-V and IELK1-1-72-30.0-91-V?
A: Both parts are identical in electrical and mechanical specifications. IEG6-1-72-30.0-91-V carries CSA, TUV, and UL1077 approvals. IELK1-1-72-30.0-91-V carries UL1077 approval only. Select based on required certification standards.
Q: Are all substitute parts available in the same packaging as the original?
A: The original MM1-B-14-630-A-2AB-B-N packaging is listed as "-" (unspecified). All substitute parts are supplied in Bulk packaging. Confirm packaging requirements with procurement specifications.
Q: Do substitute parts have the same lead times as the original?
A: Lead time information is not provided in the technical parameters. Contact suppliers directly for current lead time data.
Q: Are there any mechanical interface differences between the original and substitutes?
A: All parts share identical mounting type (Panel Mount), actuator type (Lever), and pole configuration (1P). Mechanical interface compatibility is confirmed across all parts.
Q: What is the moisture sensitivity level for substitute parts?
A: All substitute parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
Q: Can substitute parts be mixed in the same system?
A: Yes, all substitute parts meet identical electrical and mechanical specifications. Mixed deployment is permissible when approval agency certifications do not conflict with system requirements.
