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.

A leaky capacitor has the effect of a large rated capacitor that leaks and keeps the circuit from working properly. In most cases, you can over rate a capacitor and get away with it. If you double the voltage value of the capacitor but keep the supply voltage low you might want to also double the Farad value.
capacitors are 100 kvars, 200 kvars, and 300 kvars, up to 600 kvars. Units of less than 100 kvars are also available. If there is more than one capacitor in each leg, the capacitors are connected in parallel. For capacitors in parallel, the kvars are additive so that a bank with two (2) 200-kvar capacitors per phase would be a 1200 kvar bank.
