Type A-(IEC/DIN-EN61048) and Class-P0-(IEC/DIN-EN60252)capacitors do not have a specific fail-safe device as specified in the applicable standards for type B- or P2-capacitors. In the event of failure or overload the winding element may overheat and melt, smoke and even ignite; melted material may drip from the capacitor as well. It is therefore necessary to undertake constructional measures on the electrical device to provide reliable safety for people and property when using type A/P0 capacitors.
