Used on Suburban NT30-SB.This switch has a lower temp cut off than my original one which failed and made the heater inoperable without bypassing the switch. However, I found that the lower temp to be a good thing. Now, my bathroom doesn't become uncomfortably hot but still warms up quickly.I was able to carefully cut the side of the furnace off to gain access to the switch as well as the control board. This allowed me to change the switch without pulling the furnace out as the wires were too short to remove the switch in place.

The temperature button was a little smaller than the original limit switch but mounting was the same so so far so good

It was not universal and it said it was for the model furnace I have.
