Equivalent & Substitute Parts for MN1-B-22-620-1-1CB-B-C

Part Overview

The Carling Technologies MN1-B-22-620-1-1CB-B-C is a single-pole, magnetic hydraulic delay circuit breaker rated for 20A at 250V AC and 80V DC. This lever-actuated panel mount breaker is designed for overcurrent protection in industrial and commercial applications. The part is active in production with 969 units in current inventory stock.

Substitute parts are necessary when the original manufacturer part becomes unavailable, when supply chain constraints require alternative sourcing, or when equivalent performance specifications allow for interchangeable component selection across different product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MN1-B-22-620-1-1CB-B-C is determined by exact equivalence across 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: 1
• Illumination: None

All substitute parts listed below match these specifications exactly. Substitution is valid only when all parameters align with the original part requirements. Differences in manufacturer, series designation, or approval agency certifications do not affect functional equivalence when electrical and mechanical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are active products with current manufacturing status. Selection among equivalent parts may be based on the following factors:

Approval Agency Certifications: The original MN1-B-22-620-1-1CB-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 listed in provided data
• IELK1-1-72-20.0-01-V: UL1077
• IUG1-1-62-30.0-CQ-01: No approval agencies listed in provided data

RoHS Compliance: The original part is ROHS3 Compliant. All substitute parts are RoHS Compliant.

Inventory Availability: IELK1-1-72-20.0-01-V offers the highest current inventory at 1212 units. IEL1-1-51-20.0-01-V offers the lowest at 919 units.

Moisture Sensitivity Level: All Sensata-Airpax substitute parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can I substitute any of these parts for the MN1-B-22-620-1-1CB-B-C?

A: Yes, all listed parts are parametric equivalents. They share identical electrical ratings (20A, 250V AC, 80V DC), mechanical configuration (lever-actuated, panel mount, single pole), and breaker technology (magnetic hydraulic delay). Substitution is valid when all electrical and mechanical parameters match the original specification.

Q: What is the difference between the Carling Technologies and Sensata-Airpax versions?

A: The functional performance and electrical specifications are identical. Differences exist only in manufacturer identity, series designation, and approval agency certifications. The Carling Technologies part carries CCC approval, while Sensata-Airpax parts carry CSA and TUV certifications. Selection should account for application-specific regulatory requirements.

Q: Are there packaging differences between these parts?

A: The original MN1-B-22-620-1-1CB-B-C packaging is listed as "-" (not specified). Most Sensata-Airpax substitutes are packaged in Bulk. Packaging differences do not affect electrical or mechanical compatibility but may impact logistics and handling procedures.

Q: Which substitute part has the best availability?

A: IELK1-1-72-20.0-01-V has the highest inventory level at 1212 units in stock. IEG6-1-72-20.0-01-V and IUG1-1-62-30.0-CQ-01 also maintain strong inventory levels above 1000 units.

Q: Do all substitute parts meet the same approval standards?

A: No. The original part carries CCC, CSA, and UL1077 approvals. Substitute parts carry varying certifications. IEG1-1-63-20.0-01-V and IEG6-1-72-20.0-01-V both carry CSA, TUV, and UL1077. IELK1-1-72-20.0-01-V carries UL1077 only. IEL1-1-51-20.0-01-V and IUG1-1-62-30.0-CQ-01 have no approval agencies listed in the provided data. Verify approval requirements for your specific application before selection.

Q: What does "Magnetic (Hydraulic Delay)" mean?

A: This describes the breaker's trip mechanism. The magnetic element provides instantaneous response to high overcurrent conditions. The hydraulic delay element provides time-delayed response to moderate overcurrent conditions, preventing nuisance trips from temporary inrush currents while maintaining protection against sustained overloads.

Q: Are these parts interchangeable in existing installations?

A: Yes, provided the original installation uses the MN1-B-22-620-1-1CB-B-C and the substitute part meets all application-specific approval and certification requirements. Physical mounting compatibility is ensured by identical panel mount configuration and lever actuator type.
