Key Parameters

Substitute Part Grouping Explanation

Substitution of the BR2C10AC is determined by the following critical parameters:

• Number of Poles: 2-pole configuration
• Current Rating: 10A nominal
• Breaker Type: Thermal Magnetic operation
• Voltage Compatibility: AC and DC rated operation
• Curve Characteristic: C-curve trip characteristic
• Regulatory Compliance: CE, CSA, TUV, UL489, VDE certifications

The substitute part 2478150000 maintains functional equivalence through matching pole count, current rating, thermal-magnetic operation, and multi-standard certifications. Both parts are manufactured by Weidmüller and operate within the same electrical parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

The 2478150000 serves as the active equivalent for the obsolete BR2C10AC based on the following factors:

• Functional Parity: Both components share identical pole count (2P) and current rating (10A), ensuring direct functional replacement in circuit protection applications.
• Regulatory Alignment: The substitute part carries CE, CSA C22.2 No 5, CSA C22.2 No 235, TUV, UL489, and VDE certifications, meeting the compliance requirements of the original part.
• Product Status: The substitute is classified as active, ensuring continued availability and supply chain viability.
• Environmental Classification: Both parts maintain MSL 1 (unlimited) rating, indicating equivalent moisture tolerance.
• Trade Classification: Identical HTSUS and ECCN codes confirm equivalent tariff and export control treatment.

Frequently Asked Questions (FAQ)

Q: Can the 2478150000 directly replace the BR2C10AC in existing installations?

A: Yes. Both components are 2-pole, 10A thermal-magnetic circuit breakers manufactured by Weidmüller with identical moisture sensitivity and regulatory compliance profiles. The substitute is mounted on DIN rail with lever actuation, which must be verified as compatible with the original installation geometry.

Q: What is the significance of the C-curve designation on the BR2C10AC?

A: The C-curve indicates the trip characteristic of the circuit breaker, defining the current threshold and response time for fault conditions. The 2478150000 operates as a thermal-magnetic breaker, which provides equivalent protection for general-purpose AC/DC circuit protection applications.

Q: Are there packaging differences between these parts?

A: The BR2C10AC packaging is listed as "-" (unspecified), while the 2478150000 is supplied in bulk packaging. Both parts are available in new original condition with substantial inventory levels.

Q: Does the voltage rating difference (480V AC / 125V DC on the substitute) affect compatibility?

A: The substitute part's specified voltage ratings (480V AC, 125V DC) establish the maximum operating envelope. The BR2C10AC voltage ratings are not specified in the available data. Verification of the original application voltage requirements against the substitute's ratings is necessary before deployment.

Q: What certifications apply to both parts?

A: Both components carry EAR99 export classification and are REACH unaffected. The substitute additionally specifies CE, CSA C22.2 No 5, CSA C22.2 No 235, TUV, UL489, and VDE approvals, confirming compliance with North American and European safety standards.
