The Erko MKG KG_MKG-25-400 low-voltage three-phase gas capacitor features a cylindrical casing and double overpressure protection, which disconnects the electrical connection at the end of its service life. The insulation is made of nitrogen (N2).
The capacitor is equipped with a temperature sensor with NC contact, which opens at +60 °C, providing additional protection in case of overheating.
The capacitance units consist of double metallized polypropylene film (aluminum and zinc), with self-healing dielectric properties, very low active power losses, and operating life up to 120,000 hours. In case the enclosure's seal is compromised, it can continue to operate for up to 15,000 hours.
