Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MA1-B-14-620-A-A16-2-J are identified through parametric equivalence. The following criteria determine substitution eligibility:

• Breaker Type: Magnetic (Hydraulic Delay) protection mechanism
• Current Rating: 20A nominal trip current
• Voltage Ratings: 250V AC and 80V DC operational range
• Mounting Configuration: Panel-mount form factor
• Actuator Interface: Rocker-type manual control
• Pole Configuration: Single-pole switching architecture
• Illumination Status: Non-illuminated design

All substitute parts must match these parameters to ensure functional and mechanical compatibility within the intended circuit protection application.

Parameter Comparison

Engineering Selection Recommendations

Both the MA1-B-14-620-A-A16-2-J and IEGBX6-1-72-20.0-M6-V are active-status products with identical electrical and mechanical specifications. Selection between these parts is based on the following factors:

Carling Technologies MA1-B-14-620-A-A16-2-J: Approved under CCC, TUV, and UL489A standards. ROHS3 compliant. REACH unaffected status. Current inventory: 964 units.

Sensata-Airpax IEGBX6-1-72-20.0-M6-V: Approved under CSA, TUV, and UL1077 standards. RoHS compliant with MSL 1 (Unlimited) rating. Current inventory: 837 units.

Both parts satisfy identical electrical requirements and mechanical form factors. Certification differences reflect manufacturer-specific approval pathways. Selection should account for system-level certification requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the IEGBX6-1-72-20.0-M6-V directly replace the MA1-B-14-620-A-A16-2-J in existing installations?

A: Yes. Both parts share identical electrical ratings (20A, 250V AC, 80V DC), breaker type (magnetic hydraulic delay), mounting configuration (panel mount), and actuator interface (rocker). Mechanical and functional compatibility is established through parametric equivalence.

Q: What is the significance of the different approval agencies listed for each part?

A: Carling Technologies holds CCC, TUV, and UL489A approvals. Sensata-Airpax holds CSA, TUV, and UL1077 approvals. Both manufacturers maintain TUV certification. System-level certification requirements should determine which part is appropriate for the intended application.

Q: Are there differences in RoHS compliance between these parts?

A: The Carling part is ROHS3 compliant. The Sensata-Airpax part is RoHS compliant with MSL 1 (Unlimited) rating. Both meet environmental compliance requirements. The MSL 1 rating indicates unlimited shelf life under standard storage conditions.

Q: Do these parts have identical packaging specifications?

A: The Carling part is specified as Bulk packaging. The Sensata-Airpax part does not have packaging information provided in the technical data. Packaging requirements should be confirmed with the supplier for procurement purposes.

Q: What is the REACH status difference between these parts?

A: The Carling part is listed as REACH unaffected. The Sensata-Airpax part does not have REACH status specified in the provided data. REACH compliance verification should be obtained directly from the manufacturer if required for the application.
