3-phase capacitor POLT/POLB for reactive power compensation 50Hz, 400/440V POLB44364HD

Power factor correction capacitors – reliability and safety

POLT/POLB capacitors are an effective solution for improving the power factor in electrical installations. Designed for operation in 50Hz systems at 400/440V, they allow for reducing energy losses and lowering operating costs. The construction of these capacitors, based on Heavy Duty (HD) technology, guarantees long life and high reliability even in demanding operating conditions.

Construction and characteristics

POLB HD capacitors utilize a metallized polypropylene dielectric, which ensures low losses and self-regeneration. Filling with inert gas N2 further stabilizes the device's operation and extends its lifespan. The use of cylindrical aluminum cans with M12 mounting facilitates installation and provides solid grounding. A terminal block with screw terminals allows for easy and secure connection to the installation.

• Durability: The HD series is designed to operate under higher electrical loads, which translates to a longer lifespan.
• Safety: The overpressure disconnection system protects against internal damage and ensures a high level of safety.
• Identification: A nameplate with a QR code enables quick access to an individual test certificate, confirming product quality and protecting against counterfeiting.
• Low losses: The use of a metallized polypropylene dielectric minimizes energy losses, which translates into savings in operation.
• Self-regeneration: The polypropylene dielectric has self-regenerating properties, which increases the capacitor's resistance to damage.

Application

POLT/POLB capacitors are used in:

• Reactive power compensation in industrial and commercial installations.
• Improving the power factor to reduce energy losses and lower operating costs.
• Protecting electrical equipment against overvoltages and harmonic disturbances.
• Installations requiring high reliability and long operating time.
