Approvals and compliance

From the manufacturer's datasheet for this series

United States

  • UL

    UL Listing or Recognition means UL Solutions tested samples against the applicable UL safety standard and audits the factory that builds them. A UL file number is the usual evidence an inspector or specifier asks for in North America.

Europe

  • TÜV

    A TÜV certificate is third-party testing against the European EN standard. It is the evidence behind a CE declaration rather than a replacement for it: CE remains the manufacturer's own declaration, and the TÜV report is what makes that declaration defensible.

China

  • CCC

    China Compulsory Certification. Mandatory for the product categories in its scope; where it applies, a shipment without it is not clearable. Certification is against the GB standard the datasheet cites.

Eurasian Economic Union

  • EAC

    Conformity with the Eurasian Economic Union technical regulations, covering Russia, Belarus, Kazakhstan, Armenia and Kyrgyzstan. TP TC 004 is the low-voltage regulation and TP TC 020 the electromagnetic-compatibility one, so which number appears tells you what was assessed.
