MN2-B-24-620-1-1BA-B-E Circuit Breaker Equivalent & Substitute Parts

Part Overview

The Carling Technologies MN2-B-24-620-1-1BA-B-E is a magnetic hydraulic delay circuit breaker rated for 20A at 250V AC and 80V DC with lever-actuated panel mount configuration. This component is classified as Active product status with full compliance to CCC, CSA, TUV, and UL approval agencies. Substitute parts become necessary when original inventory is unavailable, when supply chain optimization is required, or when design flexibility permits selection from qualified alternative manufacturers while maintaining identical electrical and mechanical performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Parametric equivalency for the MN2-B-24-620-1-1BA-B-E is established through strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Current Rating: 20A (exact match required)
• Voltage Rating AC: 250V (exact match required)
• Voltage Rating DC: 80V (exact match required)
• Breaker Type: Magnetic (Hydraulic Delay) (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Actuator Type: Lever (exact match required)
• Number of Poles: 2 (exact match required)

All substitute parts listed below satisfy these parameters without exception. Substitution is valid across manufacturers (Carling Technologies to Sensata-Airpax) provided all electrical ratings, mechanical configuration, and pole count remain identical. RoHS compliance status differs between main part (ROHS3 Compliant) and substitutes (RoHS Compliant), but both designations confirm environmental regulatory adherence.

Parameter Comparison

Engineering Selection Recommendations

Approval Agency Considerations:

The main part MN2-B-24-620-1-1BA-B-E carries approval from CCC, CSA, TUV, and UL agencies. When selecting substitute parts, the following approval coverage applies:

• IEGH11-1-72-20.0-01-V and IEGS66-1-61-20.0-A-41-V provide the broadest substitute coverage with CSA, TUV, and UL1077 approvals, matching three of the four original approval agencies.

• IEG11-1-62F-20.0-A-00 provides CSA and UL1077 approvals, covering two primary regulatory bodies.

• IELHK11-1-72-20.0-01-V provides UL1077 approval only.

• IUG66-1-61-10.0-CQ-01 and IUG66-1-61-30.0-C-01 do not specify approval agencies in provided documentation.

RoHS Compliance:

All substitute parts are RoHS Compliant. The main part carries ROHS3 Compliant status. Both designations confirm environmental regulatory adherence; ROHS3 represents the most recent iteration of the RoHS directive.

Product Status:

All parts listed maintain Active product status, confirming ongoing manufacturer support and availability.

Inventory Availability:

Substitute parts demonstrate robust inventory levels ranging from 736 to 903 pieces, compared to 708 pieces for the main part. Selection based on approval agency requirements and inventory availability is supported by the data provided.

Frequently Asked Questions (FAQ)

Q: Can I substitute MN2-B-24-620-1-1BA-B-E with any of the listed Sensata-Airpax parts?

A: Yes. All listed substitute parts match the critical electrical parameters (20A, 250V AC, 80V DC), mechanical configuration (panel mount, lever actuator, 2-pole), and breaker type (magnetic hydraulic delay). Substitution is electrically and mechanically valid across all listed alternatives.

Q: What is the difference between ROHS3 Compliant and RoHS Compliant?

A: ROHS3 Compliant refers to compliance with the third iteration of the RoHS (Restriction of Hazardous Substances) directive. RoHS Compliant indicates adherence to the RoHS framework. Both designations confirm the parts meet environmental regulatory requirements for hazardous substance restrictions.

Q: Which substitute part has the best approval agency coverage?

A: IEGH11-1-72-20.0-01-V and IEGS66-1-61-20.0-A-41-V both carry CSA, TUV, and UL1077 approvals, providing the broadest coverage among substitutes. The original part includes CCC approval, which is not carried by any substitute listed.

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

A: The main part MN2-B-24-620-1-1BA-B-E is packaged in Bulk. Most substitutes are also Bulk packaged. IEGS66-1-61-20.0-A-41-V does not specify packaging in the provided documentation.

Q: What is Moisture Sensitivity Level (MSL)?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and requires no special handling or storage conditions related to moisture exposure.

Q: Can I use IUG66-1-61-10.0-CQ-01 or IUG66-1-61-30.0-C-01 if approval agencies are critical to my application?

A: These parts do not specify approval agencies in the provided documentation. If regulatory approval documentation is required for your application, confirm approval status directly with the manufacturer before selection.

Q: What makes these parts parametric equivalents?

A: Parametric equivalency is established through exact matching of all critical electrical and mechanical specifications: current rating (20A), AC voltage (250V), DC voltage (80V), breaker type (magnetic hydraulic delay), mounting configuration (panel mount), actuator type (lever), and pole count (2). All listed substitutes satisfy these parameters without deviation.
