Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MM2-B-32-610-1-2BA-B-C are identified based on electrical and mechanical parameter equivalence. The substitution criteria are strictly limited to the following parameters:

• Breaker Type: Magnetic (Hydraulic Delay) protection mechanism
• Current Rating: 10A nominal capacity
• Voltage Rating - AC: 250V maximum
• Voltage Rating - DC: 80V maximum
• Mounting Type: Panel Mount configuration
• Actuator Type: Lever operation
• Number of Poles: 2-pole switching

Parts meeting all seven of these parameters are classified as parametric equivalents and may be substituted in applications where the original part number is specified, provided that compliance certifications and regulatory requirements are satisfied for the intended application.

Parameter Comparison

Engineering Selection Recommendations

The IUGH66-1-51-20.0-Q-01 manufactured by Sensata Technologies – Airpax is a parametric equivalent to the MM2-B-32-610-1-2BA-B-C. Both components satisfy identical electrical specifications across all critical parameters: 10A current rating, 250V AC and 80V DC voltage ratings, two-pole lever-actuated magnetic hydraulic delay protection, and panel mount configuration.

Both parts maintain active product status and comply with RoHS regulations and EAR99 export classification. Both are assigned the same HTSUS commodity code (8536.20.0020), confirming functional and regulatory equivalence.

Selection between these parts should be based on application-specific requirements including:

• Approval agency certifications required by the end application (Carling: CCC, CSA, UL1077; Sensata: certifications not specified in provided data)
• Inventory availability and lead time considerations
• Mechanical form factor compatibility within the panel mount installation
• Supplier qualification and procurement requirements

Frequently Asked Questions (FAQ)

Q: What makes the IUGH66-1-51-20.0-Q-01 a suitable substitute for the MM2-B-32-610-1-2BA-B-C?

A: Both components share identical electrical and mechanical specifications: 10A current rating, 250V AC / 80V DC voltage ratings, magnetic hydraulic delay protection, two-pole lever actuation, and panel mount configuration. These parameters define functional equivalence for circuit breaker applications.

Q: Are there any differences in approval certifications between these parts?

A: The MM2-B-32-610-1-2BA-B-C carries CCC, CSA, and UL1077 certifications. Certification data for the IUGH66-1-51-20.0-Q-01 is not provided in the available technical parameters. Verification of required certifications for your specific application is necessary before substitution.

Q: Can these parts be used interchangeably in all applications?

A: Substitution is valid only when all electrical parameters (current, voltage, protection type) and mechanical parameters (mounting, actuation, pole count) match the application requirements. Approval agency certifications must also satisfy application-specific regulatory requirements.

Q: What is the significance of the magnetic hydraulic delay mechanism?

A: This protection mechanism combines magnetic instantaneous trip response for short circuits with hydraulic delay characteristics for thermal overload conditions. Both parts employ this identical protection strategy.

Q: How do RoHS compliance levels differ between these parts?

A: The MM2-B-32-610-1-2BA-B-C is ROHS3 compliant, while the IUGH66-1-51-20.0-Q-01 is RoHS compliant. Both meet RoHS regulatory requirements; the specific revision level may affect material composition in certain applications.

Q: Are there inventory considerations for selecting between these parts?

A: The MM2-B-32-610-1-2BA-B-C has 1117 units in stock, while the IUGH66-1-51-20.0-Q-01 has 1045 units available. Inventory levels may influence procurement decisions based on project timeline and volume requirements.
