    How can UL listing be better than ETL listing?

    A recent test we had completed shows a 150 TPMOV blowing up after two separate tests. This TPMOV is UL listed. This 150 TPMOV was tested at 480 volts ac at 5kA and at 480 volts ac 10 kA. Both times it was demolished. UL refused to comment, as this was not supposed to happen.
