Substitute Part Grouping Explanation

The BR1C1AC has been identified with one active substitute: the Weidmüller 2477790000 (MCB 489 series). Substitution eligibility is determined by the following critical parameters:

• Number of Poles: 1 pole configuration
• Current Rating: 1A nominal rating
• Breaker Type: Thermal-magnetic protection mechanism
• Voltage Compatibility: AC and DC voltage ratings suitable for the application
• Mounting Interface: DIN Rail mounting standard
• Product Status: Active availability ensures supply chain continuity

The 2477790000 maintains functional equivalence through identical pole count, current rating, and thermal-magnetic protection characteristics. Both components comply with the same tariff classification (HTSUS 8536.20.0020) and share equivalent regulatory standing under ECCN EAR99.

Engineering Selection Recommendations

The 2477790000 (MCB 489 series) is the designated substitute for the obsolete BR1C1AC. Selection is justified on the following engineering criteria:

Product Status & Availability: The substitute maintains active product status with confirmed inventory (805 Pcs), ensuring reliable supply for replacement and new installations.

Regulatory Compliance: Both components share identical ECCN (EAR99) and HTSUS (8536.20.0020) classifications. The substitute carries comprehensive approval certifications including CE, CSA C22.2 No 5, CSA C22.2 No 235, TUV, UL489, and VDE, providing broader regulatory coverage than the obsolete original.

Environmental & Safety Standards: The substitute is RoHS Compliant and maintains MSL 1 (Unlimited) rating, meeting contemporary environmental and moisture sensitivity requirements.

Functional Equivalence: Identical 1-pole, 1A thermal-magnetic configuration ensures direct functional replacement in existing circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can the 2477790000 directly replace the BR1C1AC in existing installations?

A: Yes. Both components share identical pole count (1), current rating (1A), and thermal-magnetic protection mechanism. The substitute is rated for 277 V AC and 60 V DC, providing adequate voltage coverage for standard branch circuit applications. Verify your application voltage requirements fall within these ratings before installation.

Q: What is the primary reason for substitution?

A: The BR1C1AC is classified as obsolete. The 2477790000 is an active product with confirmed inventory and comprehensive regulatory certifications, ensuring long-term supply chain viability and compliance with current standards.

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

A: The BR1C1AC packaging is listed as unspecified in available documentation. The 2477790000 is supplied in bulk packaging and is mounted on DIN Rail. Confirm DIN Rail compatibility with your installation framework.

Q: What certifications does the substitute carry?

A: The 2477790000 holds approvals from CE, CSA C22.2 No 5, CSA C22.2 No 235, TUV, UL489, and VDE. These certifications cover North American (UL, CSA) and European (CE, VDE, TUV) regulatory requirements.

Q: Is the substitute RoHS compliant?

A: Yes. The 2477790000 is RoHS Compliant, meeting environmental restrictions on hazardous substances. The original BR1C1AC RoHS status is not specified in available documentation.

Q: What is the moisture sensitivity level of the substitute?

A: The 2477790000 carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. This matches the original part's MSL rating.
