MN1-B-34-620-1-1CB-B-C Circuit Breaker Equivalent & Substitute Parts

Part Overview

The Carling Technologies MN1-B-34-620-1-1CB-B-C is a single-pole magnetic hydraulic delay circuit breaker rated for 20A at 250V AC and 80V DC with lever panel mount actuation. This component is classified as Active product status and holds multiple regulatory approvals including CCC, CSA, and UL1077 certification. Substitute parts become necessary when the primary manufacturer part is unavailable, when supply chain optimization is required, or when design flexibility permits equivalent functionality from alternative manufacturers. All substitute parts listed maintain identical electrical and mechanical parameters as the main part.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MN1-B-34-620-1-1CB-B-C is determined by strict parametric equivalence across the following criteria:

Mandatory Matching Parameters:

• Current Rating: 20A
• Voltage Rating AC: 250V
• Voltage Rating DC: 80V
• Breaker Type: Magnetic (Hydraulic Delay)
• Mounting Type: Panel Mount
• Actuator Type: Lever
• Number of Poles: 1
• Illumination: None

All substitute parts listed below satisfy these requirements without exception. Substitution does not require design modification, recertification, or application re-evaluation when these parameters remain constant. Differences in manufacturer, series designation, base product number, or packaging format do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status, ensuring continued manufacturer support and availability. The primary part MN1-B-34-620-1-1CB-B-C carries CCC, CSA, and UL1077 approvals. Substitute parts carry the following certifications:

IEG1-1-63-20.0-01-V: CSA, TUV, UL1077 IEG6-1-72-20.0-01-V: CSA, TUV, UL1077 IEL1-1-51-20.0-01-V: No approval agencies specified in provided data IELK1-1-72-20.0-01-V: UL1077 IUG1-1-62-30.0-CQ-01: No approval agencies specified in provided data

Selection between substitute parts should account for application-specific certification requirements. All substitute parts are RoHS compliant and carry Moisture Sensitivity Level 1 (Unlimited) where specified, indicating no moisture handling restrictions during storage or assembly. The REACH status for IEG6-1-72-20.0-01-V is documented as REACH Unaffected. All parts share identical ECCN (EAR99) and HTSUS (8536.20.0020) classifications.

Frequently Asked Questions (FAQ)

Q: Can IEG1-1-63-20.0-01-V replace MN1-B-34-620-1-1CB-B-C in existing designs?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications: 20A current rating, 250V AC / 80V DC voltage ratings, magnetic hydraulic delay operation, lever actuation, single-pole configuration, and panel mount form factor. No design modification is required.

Q: What is the difference between the Sensata-Airpax substitute parts?

A: The substitute parts differ in series designation (IEG, IEL, IUG) and base product number, but all maintain identical electrical and mechanical parameters. Series and base product number variations reflect internal manufacturer product line organization and do not affect functional performance or compatibility.

Q: Are all substitute parts available in the same packaging format?

A: No. The main part MN1-B-34-620-1-1CB-B-C is specified with packaging format "-" (not provided). Substitute parts are available in Bulk packaging (IEG1-1-63-20.0-01-V, IEG6-1-72-20.0-01-V, IEL1-1-51-20.0-01-V, IELK1-1-72-20.0-01-V) or unspecified format (IUG1-1-62-30.0-CQ-01). Packaging format does not affect component functionality.

Q: Do all substitute parts carry the same regulatory approvals?

A: No. Approval agencies vary among substitute parts. IEG1-1-63-20.0-01-V and IEG6-1-72-20.0-01-V carry CSA, TUV, and UL1077. IELK1-1-72-20.0-01-V carries UL1077. IEL1-1-51-20.0-01-V and IUG1-1-62-30.0-CQ-01 have no approval agencies specified in provided data. Application requirements determine which certifications are necessary for your specific use case.

Q: What is the inventory status of substitute parts?

A: All substitute parts are documented as New Original In Stock: IEG1-1-63-20.0-01-V (1051 Pcs), IEG6-1-72-20.0-01-V (1032 Pcs), IEL1-1-51-20.0-01-V (919 Pcs), IELK1-1-72-20.0-01-V (1212 Pcs), and IUG1-1-62-30.0-CQ-01 (1095 Pcs). The main part MN1-B-34-620-1-1CB-B-C has 1008 Pcs in stock.

Q: Are there any moisture sensitivity considerations for these parts?

A: Substitute parts with specified Moisture Sensitivity Level (MSL) are rated MSL 1 (Unlimited), indicating no moisture-related handling restrictions. The main part and IUG1-1-62-30.0-CQ-01 do not have MSL data provided.

Q: Can I use these parts interchangeably in the same circuit?

A: Yes. All parts are parametrically equivalent for the specified electrical and mechanical parameters. Interchangeability is determined by matching current rating, voltage ratings, breaker type, mounting configuration, and actuator type, all of which are identical across the main part and all substitutes.
