BR2D2AC Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The BR2D2AC is a 2-pole branch circuit breaker manufactured by Weidmüller, designed for AC/DC applications with a 2A current rating. This product is classified as obsolete, making identification of active equivalent parts essential for procurement and system continuity. The BR2D2AC operates as a thermal-magnetic protection device suitable for DIN rail mounting installations. Due to its obsolete status, sourcing active alternatives from the same manufacturer's current product lines is necessary for new designs and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

The BR2D2AC has been identified with one active equivalent part: 2478830000. Substitution eligibility is determined by the following critical parameters:

• Number of Poles: Both parts must be 2-pole configurations
• Current Rating: Both parts must be rated for 2A
• Breaker Type: Thermal-magnetic protection mechanism
• Mounting Standard: DIN rail compatibility
• Voltage Compatibility: AC and DC voltage ratings must meet or exceed the original specification
• Regulatory Compliance: Certifications and standards alignment (CE, CSA, TUV, UL489, VDE)

The substitute part 2478830000 satisfies all substitution criteria through matching pole count, current rating, breaker technology, and mounting method, while maintaining full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 2478830000 is the direct active equivalent for the obsolete BR2D2AC. Selection of this substitute is based on:

• Functional Equivalence: Identical pole count (2P), current rating (2A), and breaker technology (thermal-magnetic)
• Product Status: The substitute is active and currently manufactured, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: The substitute carries comprehensive international certifications (CE, CSA, TUV, UL489, VDE) and maintains the same ECCN and HTSUS classification
• Environmental Compliance: RoHS compliance of the substitute meets modern regulatory requirements
• Moisture Sensitivity: Both parts share MSL 1 rating, indicating no moisture sensitivity constraints

For applications requiring the BR2D2AC, the 2478830000 provides direct functional replacement with enhanced compliance documentation and active manufacturing status.

Frequently Asked Questions (FAQ)

Q: Can the 2478830000 directly replace the BR2D2AC in existing installations?

A: Yes. Both parts are 2-pole, 2A thermal-magnetic circuit breakers with DIN rail mounting. The substitute maintains functional equivalence across all critical protection parameters.

Q: What is the significance of the BR2D2AC being obsolete?

A: Obsolete status indicates the part is no longer manufactured. The 2478830000 is the active equivalent from Weidmüller's current MCB 489 series, ensuring continued availability for new designs and replacements.

Q: Are there voltage rating differences between the two parts?

A: The BR2D2AC voltage ratings are not specified in the available data. The 2478830000 is rated for 480 V AC and 125 V DC. Verify that your application voltage requirements do not exceed these ratings.

Q: What certifications apply to the substitute part?

A: The 2478830000 carries CE, CSA C22.2 No 5, CSA C22.2 No 235, TUV, UL489, and VDE certifications, providing compliance for North American and international markets.

Q: Is the packaging different between the two parts?

A: The BR2D2AC packaging is not specified. The 2478830000 is supplied in bulk packaging. Confirm packaging requirements for your procurement process.

Q: Does the substitute meet RoHS requirements?

A: Yes. The 2478830000 is RoHS compliant, meeting current environmental regulations for electronic components.
