The voltage rating of a capacitor refers to the maximum voltage the capacitor can withstand without breaking down. This rating is crucial because it ensures the capacitor operates safely and effectively within the circuit. If the capacitor is exposed to voltages beyond its rated value, it risks failure, leading to possible damage to the circuit.

In a DC circuit, a capacitor acts as an open circuit in steady-state. This means that once the capacitor is fully charged, no current flows through it, and the voltage across it remains constant. Therefore, the steady-state voltage across a capacitor in a DC circuit is equal to the voltage of the DC source connected to it.
The short circuit protection of the capacitors is provided by the switch disconnectors. For the capacitors the fuse link rated current should be 1.6 time of the rated reactive current of the capacitor. In=Q / (Un×√3) where: Q – rated power of the capacitor at rated mains voltage.
