Three-phase capacitor POLB for reactive power compensation 50Hz, 480/525V POLB44030SHD

POLB Capacitors – Effective Reactive Power Compensation

Three-phase POLB capacitors, manufactured by Lifasa (distributed by ANIRO), are a reliable solution for reactive power compensation in electrical installations. Designed for operation in 50Hz networks with a voltage of 480/525V, they allow for improvement of the power factor (cos φ) and reduction of energy losses. This reduces operating costs and increases energy efficiency. The POLB44030SHD model, with a power of 3 kVAR, is ideal for use in industrial plants, commercial facilities, and public buildings.

Construction and application

POLB capacitors are characterized by a solid construction and high quality workmanship. They are designed for mounting in capacitor banks, where they ensure stable and long-lasting operation. Their main task is to compensate for inductive reactive power generated by loads such as electric motors, transformers, and fluorescent lamps. By reducing the consumption of reactive power from the grid, POLB capacitors relieve the power grid and reduce the load on transformers and transmission lines.

• Improvement of the power factor: Increasing cos φ leads to a reduction of energy losses in the installation.
• Reduction of energy costs: Lower electricity bills thanks to more efficient use of active power.
• Grid relief: Reducing the load on transformers and transmission lines, which translates into their longer service life.
• Increased network capacity: Releasing active power for new consumers without the need to expand infrastructure.
• Application in various installations: Ideal for industrial plants, commercial facilities and public buildings.

Characteristics and installation

POLB capacitors are designed for easy installation and safe operation. They require connection to a properly secured capacitor bank with overcurrent and overload protection. It is important to properly select the capacitor power to the needs of a given installation – too little power will not provide full compensation, and too much can lead to overvoltages and damage. Professional selection and installation guarantee optimal performance and reliability of the reactive power compensation system.
