Heavy Duty (HD series) capacitor are designed to offer long term expectancy and outstanding performance with its higher electrical characteristics. It is a self-healing capacitor with low losses metallized polypropylene dielectric, filled with inert gas N2. They have an overpressure disconnection system which provides a high level of safety against internal defects cutting the 3 phases. Capacitors are built in cylindrical aluminum cans, provided with a M12 stud for fixing and earthling. Connection is made by a terminal block with clamp type terminals. The name plate includes a QR code associated, allowing you to download the individual routine test certificate, and it also offers a copy protection.
