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.

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.
