Power Capacitor POLB SHD
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.
