LPC 1 kVAr, 400V, 50Hz Capacitor 004656700

Power factor correction capacitors – optimizing installation performance

The LPC 1 kVAR, 400V, 50Hz capacitor is a key element in power factor correction systems, designed to improve the energy efficiency of electrical installations. Used in circuits with inductive loads – such as motors, transformers, or lighting – it reduces energy losses and lowers operating costs. Its task is to minimize the phase shift between voltage and current, which translates to better utilization of active power.

Construction and application

The LPC capacitor is a dry-type device filled with non-toxic polypropylene resin. This ensures excellent heat dissipation properties and long-term reliability. The construction with an internal connection in a ∆ configuration and an aluminum housing with overpressure disconnectors guarantees safety and durability. This allows the capacitor to operate in various environmental conditions. Faston connectors facilitate quick and secure installation, especially in applications requiring frequent configuration changes.

Key features and benefits

• Reactive power compensation: Improvement of the power factor (cos φ) and reduction of energy losses in the electrical network. This translates to lower energy bills and reduced load on transformers and transmission lines.
• High reliability: The use of high-quality metallized polypropylene film with self-healing properties ensures long life and resistance to failure. In the event of an insulation breakdown, local repair occurs, allowing the capacitor to continue operating with a minimal capacitance drop (approx. 100 pF).
• Safety: The built-in overpressure disconnector protects the capacitor bank from damage in the event of overload or failure of one of the elements. Additionally, discharge resistors ensure a safe reduction of voltage at the terminals to a level of 75V within a maximum of 3 minutes after disconnection from the power supply – in accordance with PN-EN-61048, PN-EN-60252 and EN-60831-1/2 standards.
• Easy installation: Faston connectors for capacitors up to 5kVAR simplify and speed up installation.
• Versatility: Possibility of mounting both in vertical and horizontal position (horizontal mounting requires additional support).
• Overvoltage protection: Internal overpressure disconnector protects against the effects of overvoltages and harmonic disturbances.

The LPC capacitor is a solid solution for both professional installers and end-users looking for an effective way to improve the quality of energy in their electrical installation. Its technical parameters – capacitance of 6.6 µF at a voltage of 400V and a frequency of 50Hz, and dimensions of 200 mm length and 60 mm diameter – make it a universal element of many power factor correction systems.
