3-phase capacitor POLT/POLB for reactive power compensation 50Hz, 400/440V POLB40500HD

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 networks with a voltage of 400/440V, they allow for reducing energy losses and network load, which translates into lower operating costs. The construction based on a metallized polypropylene dielectric ensures high reliability and long service life, even in demanding operating conditions.

Construction and characteristic features

Capacitors from the HD series are distinguished by a solid construction and advanced technical solutions. The use of inert gas N2 as a filling minimizes the risk of electric arcs and extends the service life of the device. Aluminum cans with M12 mounting guarantee stability and facilitate installation. A terminal block with screw terminals provides convenient and secure connection to the electrical installation.

• Self-healing: The polypropylene dielectric allows the capacitor to "self-repair" minor damage, increasing its resistance to failure.
• Low losses: The use of modern materials minimizes energy losses, increasing the energy efficiency of the system.
• Safety: Overpressure disconnection system protects against internal damage in the event of a failure, ensuring a high level of safety.
• Identification: A nameplate with a QR code enables quick access to an individual test certificate, confirming the quality and parameters of the capacitor and protecting against counterfeiting.
• Durability: Heavy Duty (HD) capacitors are designed to operate at elevated temperatures and with higher electrical loads, making them an ideal choice for demanding industrial applications.

Application

POLT/POLB capacitors are widely used in:

• Power factor correction installations in industrial plants,
• Low-voltage switchgear,
• Lighting systems,
• HVAC equipment (heating, ventilation, and air conditioning),
• Where improvement of the power factor and reduction of energy losses are required.
