Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MM1-B-34-620-1-2HB-B-C are qualified based on the following critical parameters that must match exactly:

Electrical Parameters (Must Match):

• Current Rating: 20A
• Voltage Rating - AC: 250V
• Voltage Rating - DC: 80V

Mechanical Parameters (Must Match):

• Breaker Type: Magnetic (Hydraulic Delay)
• Mounting Type: Panel Mount
• Actuator Type: Lever
• Number of Poles: 1

Functional Parameters (Must Match):

• Illumination: None

All identified substitute parts meet these criteria and are manufactured by Sensata-Airpax or Sensata Technologies – Airpax, representing alternative product lines within the magnetic hydraulic delay circuit breaker category. Substitution is valid across manufacturers when all electrical, mechanical, and functional parameters align.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active product status components with full regulatory compliance. Selection among equivalent parts is based on the following factors:

Regulatory Compliance: The MM1-B-34-620-1-2HB-B-C carries CCC, CSA, and UL1077 certifications. Substitute parts carry the following certifications:

• IEL1-1-51-20.0-01-V: No approval agency listed
• IELK1-1-72-20.0-01-V: UL1077
• IEG1-1-63-20.0-01-V: CSA, TUV, UL1077
• IEG6-1-72-20.0-01-V: CSA, TUV, UL1077
• IUG1-1-62-30.0-CQ-01: No approval agency listed

Environmental Compliance: The MM1-B-34-620-1-2HB-B-C is ROHS3 Compliant and REACH Unaffected. All substitute parts are RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions.

Inventory Availability: All substitute parts maintain active inventory status with quantities ranging from 919 to 1212 pieces in stock.

Frequently Asked Questions (FAQ)

Q: What parameters must match for a part to be considered a direct substitute for the MM1-B-34-620-1-2HB-B-C?

A: The following parameters must match exactly: 20A current rating, 250V AC and 80V DC voltage ratings, magnetic hydraulic delay breaker type, panel mount configuration, lever actuator, single pole configuration, and no illumination. All listed substitute parts meet these criteria.

Q: Can I use IEL1-1-51-20.0-01-V as a substitute if my application requires CSA certification?

A: No. The IEL1-1-51-20.0-01-V does not list CSA certification in its approval agency specifications. If CSA certification is required, use IEG1-1-63-20.0-01-V or IEG6-1-72-20.0-01-V, which both carry CSA and UL1077 certifications.

Q: Are all substitute parts available in the same packaging as the original MM1-B-34-620-1-2HB-B-C?

A: The MM1-B-34-620-1-2HB-B-C packaging is listed as dash (standard). Most substitute parts are available in Bulk packaging. IUG1-1-62-30.0-CQ-01 is available in dash packaging. Packaging differences do not affect electrical or mechanical compatibility.

Q: What is the difference between the IEG series and IEL series substitutes?

A: Both IEG and IEL series parts meet all electrical and mechanical parameters for substitution. The IEG series (IEG1-1-63-20.0-01-V and IEG6-1-72-20.0-01-V) carries CSA and TUV certifications. The IEL series (IEL1-1-51-20.0-01-V and IELK1-1-72-20.0-01-V) represents alternative product lines within the Sensata-Airpax portfolio. Selection depends on specific certification requirements for your application.

Q: Is the IUG1-1-62-30.0-CQ-01 a suitable substitute despite the different part number structure?

A: Yes. The IUG1-1-62-30.0-CQ-01 meets all critical electrical parameters (20A, 250V AC, 80V DC), mechanical parameters (panel mount, lever actuator, single pole), and functional parameters (magnetic hydraulic delay, no illumination). The different part number structure reflects Sensata Technologies – Airpax product line designation but does not affect substitution validity.

Q: What does RoHS Compliant status mean for these circuit breakers?

A: RoHS Compliance indicates the parts meet Restriction of Hazardous Substances regulations, restricting the use of specific hazardous materials. The MM1-B-34-620-1-2HB-B-C is ROHS3 Compliant, and all substitute parts are RoHS Compliant, confirming environmental regulatory alignment.

Q: Can I mix and match these substitute parts in the same circuit protection system?

A: Yes. All substitute parts are electrically and mechanically equivalent with identical current and voltage ratings, breaker type, mounting configuration, and actuator type. They can be used interchangeably in the same application provided certification requirements are met.
