Will this fit York TCGD60S21S2A? If LRA is higher than the current contact rating per pole, would it cause problem?

No that's not a problem. It's better! It's using a 30-amp where you need a 40-amp that is the problem. That puts more current through the contacts than they are rated for. You're putting less current through them so you are safe with regard to that issue. You might consider using an electrician if you're not sure about something like that.

Any one know are there any relays or contactors with nornally closed contacts?

Yes, see you're local appliance repair store to find the right one, if you're going to order thru Amazon, be really specific .

does it work for Trane XB1000 model TTB030C100A1? THANKS.

I am not going to research anyone's AC spec or anything else at any time. This is a 24 VAC controlled contactor with 40 amp Contacts. That is all it is.If you know how to use it, then it works good If you don't know how or are not qualified, don't do it yourself! It's not safe for you to do it if you don't know what you are doing!
