CT means "Center Tapped", hence the three leads.

I am looking at a transformer from Mouser, part number is 41PG300. In the
Mouser catalog the specs say the secondary volts is "12.6CT". What does
the
CT mean? Also, the data sheet shows 3 leads coming from the secondary.
Why
would there be 3 leads rather than just 2?
