LV steel box capacitors

LV steel box capacitors for high performance in severe conditions

VarplusBox
  • Features

    VarplusBox are low voltage metal box capacitors specially designed to deliver reliable performance in standard, heavy-duty and most severe operating conditions, in fixed and automatic Power Factor correction systems, in networks with frequently switched loads and harmonic disturbances.

    •  Technical datas:
        - High life expectancy up to 160,000 hours
        - Voltage up to 830 V
        - High power ratings up to 100 kvar
        - Operating temperature up to 70 °C
        - High inrush current withstand up to 400 x IN
        - Stand-alone equipment
        - Direct connection to a machine, in harsh environmental conditions
       - Compliant with standards IEC 60831-1 and -2

    VarplusBox capacitors must be selected depending on the working conditions expected during their lifetime. Since the harmonics are caused by non-linear loads, an indicator for the magnitude of harmonics is the ratio NLL of the total power of non-linear loads to the power supply transformer rating.
