POLB HD 50 Hz
Power Capacitor POLB HD 50 Hz
Heavy Duty (HD series) capacitors are designed to offer long time 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.
