3-phase capacitor POLT/POLB for reactive power compensation 50Hz, 400/440V POLB44200HD

Power factor correction capacitors – an effective solution for your installation

POLT/POLB capacitors are reliable devices designed for reactive power compensation in power networks with a voltage of 400/440V and a frequency of 50Hz. They are a key element in improving energy efficiency, reducing network losses, and lowering electricity costs. The POLB44200HD model, from the Heavy Duty series, stands out for its high durability and efficiency, making it an ideal choice for both demanding industrial installations and commercial facilities.

Construction and characteristic features

POLB HD capacitors are characterized by a solid construction based on a self-regenerating metallized polypropylene dielectric. Filling with inert gas N2 ensures stability of operating parameters and long life. They are equipped with an overpressure disconnection system, which provides additional protection against internal damage, increasing safety. The aluminum cans of the capacitors have an M12 screw for convenient mounting and grounding. Electrical connections are made using a terminal block with screw terminals, which facilitates installation and ensures a secure connection. Additionally, the nameplate contains a QR code providing access to an individual test certificate – a guarantee of quality and compliance with standards.

Application and benefits

POLB capacitors are widely used in:

• Industry: Reactive power compensation in induction motors, transformers and other energy-consuming equipment.
• Commercial construction: Improving the power factor in offices, shopping centers and other service facilities.
• Energy installations: Voltage stabilization in the network and reduction of energy losses.
• Automatic power factor correction (APFC) systems: As a component of APFC systems ensuring optimal reactive power compensation under variable load conditions.

By choosing POLB capacitors, you gain:

• Reduced energy costs: Improving the power factor reduces reactive power consumption, thereby lowering electricity bills.
• Increased energy efficiency: Reactive power compensation unloads the power grid and improves its efficiency.
• Extended device life: Voltage stabilization reduces the load on electrical equipment, which translates into their longer life.
• Safety: The overpressure disconnection system provides protection against internal damage to the capacitor.
• Easy identification: The QR code on the nameplate allows quick access to the test certificate confirming the product quality.
