BR3C15AC Equivalent & Substitute Parts
Part Overview
The BR3C15AC is a 3-pole branch circuit breaker with C-curve characteristics and 15A current rating, manufactured by Weidmüller. This product is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance and component procurement. The BR3C15AC serves as a thermal-magnetic protection device for AC/DC applications and requires substitution with active-status equivalents that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation
Substitution of the BR3C15AC is based on the following critical parameters that must remain constant:
- Number of Poles: 3-pole configuration
- Current Rating: 15A
- Breaker Type: Thermal-magnetic protection
- AC/DC Compatibility: Dual voltage operation capability
- Manufacturer: Weidmüller (same manufacturer ensures design continuity)
- Regulatory Compliance: Certifications and standards alignment
The substitute part 2478430000 (MCB 489 series) meets these criteria as an active-status alternative from the same manufacturer, providing direct functional equivalence with updated product availability.

- Product Availability: Active manufacturing status ensures long-term procurement reliability
- Environmental Classification: Maintains MSL 1 rating and REACH unaffected status
- Trade Classification: Identical HTSUS code (8536.20.0020) and ECCN (EAR99) classification
- RoHS Compliance: Meets current environmental standards with RoHS compliance
Frequently Asked Questions (FAQ)
Q: Can the 2478430000 directly replace the BR3C15AC in existing installations?
A: Yes. Both parts share identical electrical specifications (3-pole, 15A, thermal-magnetic, AC/DC operation) and are manufactured by Weidmüller. The substitute features DIN Rail mounting and lever actuation, which are standard for this product category.
Q: What is the significance of the MCB 489 series designation?
A: MCB 489 identifies the active product series within Weidmüller's circuit breaker portfolio. The "489" designation indicates the current generation of miniature circuit breakers that supersede earlier branch circuit breaker designs like the BR3C series.
Q: Are there packaging differences between these parts?
A: The BR3C15AC packaging is listed as "-" (unspecified), while the 2478430000 is supplied in Bulk packaging. Both parts maintain identical electrical and mechanical form factors suitable for DIN Rail installation.
Q: Does the substitute part maintain the same voltage rating?
A: The BR3C15AC voltage rating is not specified in the available data. The 2478430000 is rated for 277 V AC operation, which is standard for 3-pole industrial circuit breakers and covers typical North American and international distribution voltages.
Q: What certifications apply to the substitute part?
A: The 2478430000 holds CE, CSA C22.2 No 5, CSA C22.2 No 235, TUV, UL489, and VDE certifications, providing compliance across North American, European, and international standards.
Q: Is the substitute part RoHS compliant?
A: Yes. The 2478430000 is RoHS compliant, meeting current environmental and hazardous substance restrictions. The original BR3C15AC RoHS status is not specified.
