Where can I buy a replacement for CR453CB3HBAFG contactor - I am in Pittsburgh PA

If this is a 30 amp 2 pole, 24 volt coil Contactor, there are many replacements.
What current, coil volts do you need?
I can't find that Part number.

I'm a complete newbie at this, so I apologize in advance.

I'm going to have to confirm this by actually getting the contactor out and verifying it, but from Google, I believe this is a single pole GE part # CR453CB3HBAFG (B13603-21) contactor with the following specs:

VAC: 240/277
FLA: 25
LRA: 150
RES: 35
