UL Standard for Safety Capacitors The requirements in Part I of this Standard apply to enclosed capacitors with integral protection intended to reduce the risk of rupture and venting of the capacitor enclosure under internal fault.
The so-called self-healing capability is not the same as fail safe system stability. 4. Most internal protective devices can inter-rupt the voltage only within the capacitor. They are not fuses in the classical sense such as cable or device fuses which inter-rupt the voltage upstream from the faulty system component. 5.
Capacitors must never be stored or used Capacitors may not be stored or operated in corrosive atmospheres, particularly not salts, organic solvents or similar substan-ces are present. In dust and dirt-prone environments, regu-
Even if the test based on the capacitor standard is passed, this does not ensure comprehensive protection against all pos-sible overloading. Currently, a number of customers are requesting special tests on unprotected capacitors with extreme overvoltages and temperatures to prove safe capacitor per-formance.

Power capacitors can actively fail when internal or external protective devices are missing, incorrectly dimensioned or have failed.
There are also safety caps that combine aspects of X and Y types, such that they have met both X and Y safety requirements and standards. So for an X1/Y1 combination, this simply means that the capacitor can be used either as an X1 capacitor in a line-to-line application or as a Y1 capacitor in a line-to-ground application. Class X1/Y2
