Power capacitor POLT 

Self-healing capacitors with low losses metalized polypropylene dielectric without liquid impregnates. They have an overpressure disconnection system that disconnects the capacitor in case of any internal failure. Capacitors in cylindrical aluminium cans, provided with a M12 stud for fixing and earthling.

Connection is made by a double 6.35 mm Faston terminal. Optionally, provided with discharge resistors for external connection. These capacitors are especially suitable for the individual compensation of small inductive loads and the construction of small capacitor banks. They have discharge resistors externally fitted.

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.
