What is the difference between the UZ-32 and UZ-32 (34A) version?

If you refer to the contactor catalog you may notice that there is a UZ-32 and a UZ-32 (34A). See below.



The difference, as you will find below, is in the the terminal screws. They are larger on the 34A version to allow larger gauge wire.
