Frequently Asked Questions (FAQ)

Q: Can the 2478200000 directly replace the BR2C20AC in existing installations?

A: Yes. Both components share identical current ratings (20A), pole configuration (2-pole), and thermal-magnetic protection principles. The 2478200000 is designed as the active-product successor to the obsolete BR2C20AC within the Weidmüller product line.

Q: What are the voltage specifications for the BR2C20AC?

A: Voltage ratings for the BR2C20AC are not specified in the available technical documentation. The substitute part 2478200000 is rated for 480 V AC and 125 V DC operation. Verification of the original BR2C20AC voltage specifications against your system requirements is recommended before substitution.

Q: Does the 2478200000 require different mounting hardware or installation procedures?

A: The 2478200000 is specified for DIN Rail mounting with a lever actuator. Confirm that your installation supports DIN Rail mounting and lever-type actuation before component substitution.

Q: Are there any regulatory or compliance differences between the two parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.20.0020) classifications. The 2478200000 carries additional international approvals (CE, CSA, TUV, UL489, VDE) and is RoHS Compliant, providing enhanced regulatory documentation compared to the obsolete BR2C20AC.

Q: What is the packaging format for the substitute part?

A: The 2478200000 is supplied in bulk packaging, differing from the BR2C20AC packaging specification. Confirm bulk packaging compatibility with your procurement and inventory management procedures.
