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.

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.

Reproduced unedited from the manufacturer's datasheet. Where an approval covers only some models, the wording says so. Ask us for the certificate itself if your approval process needs it.

Series FAQ

Do I need to derate this supply inside a sealed enclosure?

Yes. The published current rating assumes free air convection at 100 percent load up to 50 C. Inside a sealed enclosure the internal air sits above ambient, so size against the temperature at the supply, not the room.

Why does the breaker trip when several supplies switch on together?

Cold-start inrush is many times the running current and lasts only milliseconds. Stagger the switch-on, or select a breaker with a slower magnetic curve.

What is the lead time on stocked part numbers?

Stocked part numbers ship within two business days. Anything not in stock is quoted with a firm date before the order is confirmed.
