These UL contact ratings are listed in the datasheet for a Tyco relay: T90 Series, 30A PCB Relay.
(Note: the link will ask you to download the PDF, as do most Tyco PDF links)
The contact life is different for different loads and this is as expected. However, if you look at the ratings for the 'ballast' load type notice that at 6A it's specified to 100,000 cycles yet at 3A it's only 6,000. Why so?
Don't lower currents usually increase contact life? Furthermore, for CFLs, should I be looking at "ballast" load-type?
