These capacitors are designed for operation in demanding conditions where high overload values can be expected: voltage, current (harmonics), temperature. It offers an ideal solution for detuned capacitor banks with harmonic reactors, which are installed in the above-mentioned demanding operations.
Heavy Duty capacitors are characterized by long life, resistance to voltage and current overload, as well as exposure to high temperatures. The declared values significantly exceed the requirements of IEC 60831 standards.
Safety is ensured by using an overpressure disconnector that disconnects the capacitor in all 3 phases.
