The custom-tailored capacitors of our E70 series are mainly applied for power factor correction or as resonance capacitors in induction furnaces that are operated at mains frequency (50/60Hz). The E70 are made alternatively in two designs: Inside the steel case, there is a large number of individual self-healing capacitors, each one of them protected by its own break-action mechanism. In the event of a failure, the affected element is disconnected separately while the capacitor as a whole continues to function with slightly decreased total capacitance. Windings assembled inside a hermetically sealed metal case, filled with solid resin, and protected by a pressure sensor similar to the capacitors of our ranges E56/E59.

Our capacitors of the E12 and E33 series are universally-suited for lighting and motor applications as well as power factor correction and power electronics. Their winding element of self-healing polypropylene film is immersed in eco-friendly vegetable oil and designed for highest requirements regarding operational life and functional safety even at high operating temperatures and other extreme conditions such as high humidity. Connection is made through tab connectors. The hermetical aluminium can is provided with an integrated overpressure safety mechanism (break-action mechanism, " BAM ") that disconnects the capacitor irreversibly from the supply in the event of a failure. The E12/E33 ranges comply with the "Type B" classification under lighting standard IEC/EN61048 as well as with "Class P2" under motor capacitor standard IEC/EN 60252-1. Please mind our safety remarks on the use of lighting capacitors in critical environment.
