3-phase capacitor POLT/POLB for reactive power compensation 50Hz, 400/440V POLB44500HD

Power factor correction capacitors – an effective solution for your installation

POLT/POLB capacitors are components used to compensate for reactive power in electrical installations. They improve the power factor (cos φ), which translates to reduced energy losses, lower operating costs, and better utilization of connected power. The POLB44500HD model, designed to operate in 400/440V networks at a frequency of 50Hz, is a solid and reliable component that can be used in both industrial and commercial facilities.

Construction and characteristic features

HD (Heavy Duty) series capacitors are distinguished by their high durability and efficiency even in harsh working conditions. They utilize self-healing metallized polypropylene dielectric technology filled with inert gas N2. This construction ensures low energy losses and a long service life. Additionally, these capacitors are equipped with an overpressure disconnection system – protection against internal damage in the event of a failure. The housing made of cylindrical aluminum cans has an M12 screw for secure mounting and grounding. Electrical connections are made using a convenient terminal block with screw terminals.

Application and benefits

POLB capacitors are ideal for:

• Improving the power factor: Reducing the consumption of reactive power by current receivers, which leads to lower electricity bills.
• Reducing network load: Relieving transformers and transmission lines, increasing their lifespan and reliability.
• Protecting devices: Stabilizing the voltage in the network, which protects sensitive electrical devices from damage caused by voltage fluctuations.
• Modernizing existing installations: Easy integration with existing reactive power compensation systems.
• New projects: Optimizing energy efficiency from the very beginning of the project.

An additional advantage is the nameplate equipped with a QR code, enabling quick access to an individual test certificate and ensuring protection against counterfeiting. This confirms the quality and compliance with the manufacturer's standards.
