Unfortunately our company paid to have another company test the device as we didn't believe it to be reliable, so the video we have is not available for public, however we presented it to UL as 2 separate TPMOV blew up. They did not want to discuss it with us though.
2) When building a product to be UL listed, only UL listed parts will be approved.
I have heard of UL fining people for using devices other than UL listed in this case being fined, but I have also heard that is illegal for UL to fine them. Any information about this?
It amazes me that a product UL Listed will blow up when tested, this is not very safe. It obviously could not pass the test to prevent injuries because had that particular unit blown up that violently with a customer around there would have been major injuries. Also Schneider products APC...
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.
