Substitute Part Grouping Explanation

The substitute part 2479190000 qualifies as a direct equivalent based on the following matching parameters:

• Current Rating: Both parts rated at 20A
• Number of Poles: Both are 3-pole configurations
• Breaker Type: Both are thermal-magnetic circuit breakers with D-curve characteristic
• Voltage Rating: 277V AC/DC operational capability
• Actuator Type: Lever-operated mechanism
• Mounting: DIN Rail standard mounting
• Compliance: Both maintain MSL 1 (Unlimited) and REACH Unaffected status
• Tariff Classification: Identical HTSUS code 8536.20.0020

The primary distinction is product status: BR3D20AC is obsolete while 2479190000 is active, making the latter the recommended sourcing option for new applications and replacements.

Parameter Comparison

Engineering Selection Recommendations

Part 2479190000 is the direct substitute for BR3D20AC based on electrical and mechanical parameter alignment. Selection of the active part is justified by:

• Identical current rating, pole configuration, and breaker characteristic
• Maintained compliance with CE, CSA C22.2 No 5, CSA C22.2 No 235, TUV, UL489, and VDE certifications
• Active product status ensuring continued availability and supply chain reliability
• RoHS Compliance confirmation for 2479190000
• Equivalent regulatory classification (ECCN EAR99, HTSUS 8536.20.0020)

No additional testing or verification is required when substituting BR3D20AC with 2479190000 in applications where the original part was specified, provided the 277V AC rating and DIN Rail mounting are compatible with the installation environment.

Frequently Asked Questions (FAQ)

Q: Can 2479190000 directly replace BR3D20AC in existing installations?

A: Yes. Both parts share identical current rating (20A), pole count (3), breaker characteristic (D-curve), and thermal-magnetic operation. The substitute maintains all relevant compliance certifications and regulatory classifications.

Q: What is the significance of BR3D20AC being obsolete?

A: Obsolete status indicates the part is no longer manufactured. 2479190000 is the active equivalent, ensuring continued component availability for maintenance and new installations.

Q: Are there any packaging differences between these parts?

A: BR3D20AC packaging is listed as unspecified in available data. 2479190000 is supplied in Bulk packaging. Both are suitable for DIN Rail mounting applications.

Q: Do both parts meet the same electrical safety standards?

A: 2479190000 carries explicit approval from CE, CSA C22.2 No 5, CSA C22.2 No 235, TUV, UL489, and VDE. BR3D20AC maintains REACH Unaffected and EAR99 ECCN status. Both share identical HTSUS classification, confirming regulatory equivalence.

Q: Is RoHS compliance a consideration for this substitution?

A: 2479190000 is confirmed RoHS Compliant. This represents an improvement over the obsolete BR3D20AC and is suitable for applications requiring RoHS-compliant components.
