Three-phase capacitor POLB for reactive power compensation 50Hz, 480/525V POLB52500HD

Power factor correction capacitors – reliability and safety

POLB HD capacitors are components designed to improve the power factor in electrical installations. They are used to compensate for reactive power, which translates to reduced energy losses, lower operating costs, and improved device performance. The design of these capacitors is intended for long-term and trouble-free operation, even in demanding conditions.

Construction and characteristics

POLB HD capacitors utilize advanced metallized polypropylene dielectric technology, ensuring low energy losses and high reliability. Filling with inert gas N2 further stabilizes the capacitor's operation and extends its lifespan. The cylindrical aluminum housing is durable and resistant to mechanical damage. Equipped with an M12 screw, it facilitates mounting and ensures reliable grounding.

• Self-healing: The polypropylene dielectric has self-healing properties, meaning that minor damage can be repaired during operation, increasing the capacitor's durability.
• Safety: An overpressure disconnection system protects against internal damage in the event of a failure, minimizing the risk of hazards to the installation and personnel.
• Easy installation: A terminal block with screw terminals enables quick and secure connection to the electrical installation.
• Individual test certificate: Each capacitor has a nameplate with a QR code, allowing you to download an individual test certificate – a guarantee of quality and compliance with standards. The QR code also protects against counterfeiting.
• Durable construction: The aluminum can provides solid protection of the internal elements against external factors.

Application and parameters

POLB HD capacitors are designed to operate in 50Hz networks at a voltage of 480/525V. They will be useful in various industrial and commercial applications where reactive power compensation is required:

• Electrical installations in industrial plants
