Standard range or special design? Large capacitances right as you will.

Thanks to the special kind of films and coating patterns used in our AC capacitors of the E59 series, clever winding geometries and refined internal construction, they unite large capacitance and high surge current sustaining capability (up to 200 kA). The capacitors can provide a reactive power of up to 500 kvar. Depending on design, up to 500 A rms are possible.

Instead of flat pack windings, our capacitance is formed by compact cylindrical windings, avoiding the mechanical stress and instabilities at the edges of flat packs.

They are extremely overvoltage-proof. They are especially suited for filter circuits and such like. The capacitors are housed in aluminium or steel cases and filled with solid resin which makes them absolutely dry and leakage-proof. Their shape and dimensions can be adapted to the individual requirements of our customers.

Even at high operating temperatures, and after numerous self-healing dielectric breakdowns, the capacitance remains stable.

An irreversible pressure switch can be used for external monitoring of the internal pressure. It signals 0.5 atmospheres of pressure rise by closing (or optionally: opening) the contact, allowing for safe external disconnection in the event of overload or failure at the end of operating life.

Ranging from 300 to 17,000 V AC; capacitance up to 80 mF.
