Why is a capacitor considered a short circuit at start up?
In the case where a DC voltage is applied to a capacitor we are assuming that the capacitor has been previously discharged. The voltage across a capacitor can not change instantaneously so the initial voltage across the capacitor is 0. The capacitor then charges to the value of the input voltage and current stops flowing.

Capacitor in Electronics – What It Is and What It Does
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.

What happens if I connect a low voltage rated capacitor to a high voltage?
For a capacitor, one of the limits is keeping the voltage low enough that the capacitor dielectric stays intact. As you increase the terminal voltage, the electric stress increases across the dielectric, and eventually, it breaks down. When that happens, you don''t have a capacitor any more. In the best case you are left with a short circuit or ...
