These capacitors are designed to operate in extremely harsh environments where very high overload levels (voltage, current (harmonics), and temperature) can be expected. They provide an ideal solution for so-called harmonic PFC capacitor banks, equipped with reactors, installed in the aforementioned heavy-duty operations. Ultra Heavy Duty capacitors offer long-term durability, resistance to overvoltage and overcurrent, as well as high temperatures. The declared values significantly exceed the requirements of IEC 60831.
The capacitor casing is protected against explosion by an overpressure isolator – a 3-phase separation.
