Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BA1-B0-36-615-121-C is determined by the following critical parameters that must remain constant across equivalent parts:

Fixed Parameters (Must Match):

• Breaker Type: Magnetic (Hydraulic Delay)
• Current Rating: 15A
• Mounting Type: Panel Mount
• Actuator Type: Lever
• Number of Poles: 1
• Illumination: None

Variable Parameters (Allowed Variance):

• Voltage Rating - AC: 250V to 277V (downrating acceptable)
• Voltage Rating - DC: 80V (constant)
• Approval Agencies: Subset or superset of CCC, CSA, UL
• Packaging: Bulk or standard
• Moisture Sensitivity Level: Not specified in main part

The substitute part BA1-B2-24-615-122-D meets all fixed parameter requirements and maintains functional equivalence through identical breaker topology, current capacity, and mechanical interface specifications. The AC voltage rating of 250V represents a downrating from 277V, which is acceptable for applications operating at or below 250V AC.

Parameter Comparison

Engineering Selection Recommendations

Both the BA1-B0-36-615-121-C and BA1-B2-24-615-122-D are Active status products with full RoHS3 compliance and REACH Unaffected designation. The primary distinction between these parts is the AC voltage rating: the main part is rated for 277V AC, while the substitute is rated for 250V AC.

Selection between these parts is determined by the application voltage requirement. For circuits operating at 277V AC, the BA1-B0-36-615-121-C is the appropriate selection. For circuits operating at 250V AC or lower, the BA1-B2-24-615-122-D provides equivalent functionality with identical current handling, DC voltage rating, and mechanical characteristics.

The substitute part includes VDE approval in addition to CCC, CSA, and UL certifications, providing expanded regulatory coverage. Both parts share identical ECCN (EAR99) and HTSUS (8536.20.0020) classifications, confirming equivalent trade and export compliance status.

Frequently Asked Questions (FAQ)

Q: Can BA1-B2-24-615-122-D be used in place of BA1-B0-36-615-121-C in all applications?

A: The BA1-B2-24-615-122-D is suitable for applications operating at 250V AC or lower. For circuits requiring 277V AC operation, the BA1-B0-36-615-121-C must be used. Both parts are identical in all other electrical and mechanical specifications.

Q: What is the significance of the voltage rating difference between these parts?

A: The BA1-B0-36-615-121-C is rated for 277V AC maximum, while the BA1-B2-24-615-122-D is rated for 250V AC maximum. A lower-rated part can be used in lower-voltage applications but not in higher-voltage applications. Verify the circuit voltage before selecting either part.

Q: Are there packaging differences between these substitute parts?
