MM2-B-34-620-1-2AA-B-C Circuit Breaker Equivalent & Substitute Parts

Part Overview

The MM2-B-34-620-1-2AA-B-C is an active-status magnetic hydraulic delay circuit breaker manufactured by Carling Technologies. This two-pole lever-actuated panel mount breaker is rated for 20A at 250V AC and 80V DC. Finding equivalent substitute parts is necessary when the primary part becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits component standardization across multiple suppliers while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MM2-B-34-620-1-2AA-B-C are qualified based on matching the following critical parameters:

• Breaker Type: Magnetic (Hydraulic Delay)
• Current Rating: 20A
• Voltage Rating - AC: 250V
• Voltage Rating - DC: 80V
• Mounting Type: Panel Mount
• Actuator Type: Lever
• Number of Poles: 2
• Illumination: None

Both substitute parts listed below satisfy all of these electrical and mechanical requirements. Substitution is valid when these parameters align exactly with the main part specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed maintain active product status and comply with applicable regulatory frameworks. The MM2-B-34-620-1-2AA-B-C carries CCC, CSA, and UL1077 approvals. Both substitute parts carry UL1077 approval and are RoHS compliant. All parts share identical electrical ratings, mechanical configuration, and HTSUS classification.

Selection between the main part and substitutes depends on availability, supply chain requirements, and packaging specifications. The IELHK11-1-72-20.0-01-V and IUG66-1-61-30.0-C-01 are functionally interchangeable with the MM2-B-34-620-1-2AA-B-C for applications requiring a 20A, 250V AC / 80V DC, two-pole magnetic hydraulic delay circuit breaker with lever actuation and panel mount configuration.

Frequently Asked Questions (FAQ)

Q: What makes these parts equivalent to the MM2-B-34-620-1-2AA-B-C?

A: All three parts share identical electrical ratings (20A, 250V AC, 80V DC), mechanical configuration (two-pole, lever-actuated, panel mount), and breaker technology (magnetic hydraulic delay). These parameters define functional equivalence for circuit breaker applications.

Q: Can I substitute the IELHK11-1-72-20.0-01-V or IUG66-1-61-30.0-C-01 directly into an existing design using the MM2-B-34-620-1-2AA-B-C?

A: Yes. Both substitute parts match all critical electrical and mechanical parameters. Physical dimensions and mounting interface compatibility should be confirmed through mechanical drawings if not provided in this reference.

Q: What is the difference between the two Sensata-Airpax substitutes?

A: Both IELHK11-1-72-20.0-01-V and IUG66-1-61-30.0-C-01 meet identical electrical and mechanical specifications. They differ in series designation (IEL versus IUG) and packaging. Selection between them depends on inventory availability and packaging requirements.

Q: Are there any compliance differences between the main part and substitutes?

A: The MM2-B-34-620-1-2AA-B-C carries CCC, CSA, and UL1077 approvals. Both substitutes carry UL1077 approval and are RoHS compliant. All parts are classified under HTSUS code 8536.20.0020 and carry EAR99 ECCN designation.

Q: What packaging options are available?

A: The MM2-B-34-620-1-2AA-B-C is supplied with standard packaging. The IELHK11-1-72-20.0-01-V and IUG66-1-61-30.0-C-01 are supplied in bulk packaging. Packaging selection should align with procurement and logistics requirements.

Q: How do I confirm mechanical compatibility before substitution?

A: Verify panel cutout dimensions, mounting hole spacing, terminal configuration, and actuator lever geometry against the original design specifications. Electrical equivalence is confirmed by matching all parameters in the Key Parameters table.
