Need help determining single or double pole contactor

I would know if I saw it again but can't remember 100%. Reason I ask is I need to get this part but won't be able to get to the house to see it and need to change it out tomorrow evening.

This is a Trane outside AC unit, no heat..has gas. Model # TTR042C100A0

I'm almost certain it was a single 30A but can you tell by the model #?

Thanks....I know I could buy both but likely cannot return electrical parts.

If at all possible , I replace with a 2 pole contactor and if there is enough physical room ( there usually is ) the next size up in ampacity .

Such an upgrade cost me very little more and it is hoped will last longer .

A 2 pole contactor may wire SLIGHTLY differently . But no big deal .

The web sire shows contractor cost at less than $ 10 .

God bless
