Discharge Reactor EL-DR
The increasing demand for shorter discharge periods cannot be satisfied by traditional discharge means (fixed
resistors). The installation of additional fast discharge resistors at the capacitor contactor results in increased
expenses for material and installation. Our discharge reactor replaces the compulsory fixed resistors and additional rapid discharge resistors, and at the same time it substantially reduces the heat losses inside the capacitor
bank. It further avoids additional heating of the capacitor terminals by standard discharge resistors.

Protective Caps (design A)
Plastic protective caps are available to protect the capacitor
terminals from accidental contact or the influence of dust
and water.
For diameters up to 60mm, the caps are fitted to the capacitors during manufacture. In this case, cable and integral
discharge resistors are also fitted, to give an IP54 rating.
For capacitors in design A with diameters of 65 and 75mm,
the caps are supplied loose if ordered. Note that these caps
do not comply with IP classification.
