In electrical distribution, it's called a shorting bar, a shunt, a bypass, or a jumper.

The CT could be considered to be "impedance protected", since its maximum current is limited by its internal impedance.

In the case of an 80:5 CT, only a primary overload can increase the secondary current beyond the 5-amp maximum design current.
