Insulation Resistance and Dielectric Withstanding Voltage …
The BDV is the voltage where the part arcs across the metallic interface; think pin-to-pin or pin-to-hardware, and working voltage is = 1/3 x DWV or 0.25 x BDV. For example: if the breakdown voltage is 1000 VAC the Test Voltage will be 750 VAC, and Working Voltage will be 250 VAC. DWV is tested by applying the calculated test voltage …
Dielectric strength

What does the Voltage Rating on a Capacitor Mean?
Also, note that the voltage rating of a capacitor is also referred to at times as the working voltage or maximum working voltage (of the capacitor). So when seeing the (maximum) working voltage specification on a datasheet, this value refers to the maximum continouous voltage that a capacitor can withstand without becoming damaged.
