When a capacitor is switched to an AC voltage, the result is a resonant circuit damped to a greater or lesser degree. The switching of capacitors can cause high inrush currents, particularly when they are switched in parallel to others already activated in the power line, and if high short-circuit powers are present on the line. Capacitor contactors with damping resistors make use of pre-switching auxiliary contacts. They close before the main contacts and pre-load the capacitor thus avoiding current peak values. This influences positively the life expectancy of the capacitor significantly in addition to the positive impact on the power quality (avoiding transients and voltage sags that otherwise may be caused by switching in capacitors).

The capacitor duty contactors are offered in two versions, viz
  • Standard series 
  • Premium series (imported)

  • Damping of inrush current in low-voltage PFC systems
  • For PFC systems with and without reactors

  • Excellent damping of inrush current
  • Improved power quality (e.g. avoidance of voltage sags)
  • Longer useful service life of main contacts of capacitor contactor
  • Soft switching of capacitor and thus longer useful service life
  • Enhanced mean life expectancy of PFC system
  • Reduced ohmic losses
  • Leading contacts with wiper function
  • Tamper-proof and protected resistors
  • Easy access for cable connection
  • Series J230 / C240 for all PFC systems
  • AC6b utilization category

  • UL file E224924 NLDX and NLDX 7 for J series
  • UL file E334934 NLDX and NLDX 7 for C series
