Frequently Asked Questions (FAQ)
Q: What makes 2478500000 a suitable substitute for BR3C40AC?
A: Both components share identical critical specifications: 3-pole configuration, 40A current rating, 240V AC/DC voltage rating, thermal magnetic protection, and lever actuation. Both are manufactured by Weidmüller and carry equivalent regulatory certifications.
Q: Is the 2478500000 available in the same packaging as BR3C40AC?
A: BR3C40AC packaging is not specified in available data. The 2478500000 is supplied in bulk packaging and is mounted on DIN rail. Verify mounting compatibility with your installation requirements.
Q: Are there any compliance differences between the two parts?
A: Both components are REACH Unaffected and classified under ECCN EAR99. The 2478500000 carries explicit RoHS Compliance certification. Both share the same HTSUS code 8536.20.0020.
Q: Can 2478500000 be used as a direct replacement in existing installations?
A: Substitution is valid where 3-pole, 40A, 240V AC/DC thermal magnetic circuit breaker functionality is required. Confirm DIN rail mounting compatibility with your existing installation before proceeding.
Q: What is the inventory status of these parts?
A: BR3C40AC (obsolete): 920 pieces in stock. 2478500000 (active): 1056 pieces in stock. Availability of BR3C40AC will diminish as inventory depletes; transition to 2478500000 is recommended for new designs and future procurement.
