The K3-74K00-230V contactor from Benedict GmbH is designed for reliable and efficient switching of capacitive loads in reactive power compensation systems. With a power rating of 75 kVAr and a nominal voltage of 230 V AC, it features bias contacts and damping resistors that reduce inrush currents to less than 70 times the rated current (Ie), protecting both the equipment itself and the connected systems. Rated current 108 A, DIN rail mountable, rated voltage: 400 V AC. Ideal for industrial applications and reactive power compensation panels, the K3-74K00 allows for a high switching frequency of up to 80 switches per hour and long life even with frequent switching.

Objednací číslo: K3-74K00

The K3-74K00-230V contactor is engineered for the reliable and efficient switching of capacitive loads in reactive power compensation systems. With advanced precharge contacts and damping resistors, it reduces inrush current to less than 70 times the nominal current (Ie), protecting not only the device itself but also connected systems. This model is designed for use with low-inductive and low-loss capacitors in compliance with IEC 831 and VDE 0560 standards.

Detailed Description

The K3-74K00-230V contactor is specifically tailored for applications involving reactive power compensation in three-phase capacitor banks, suitable for both reactive and non-reactive elements. Its robust construction enables efficient switching of high currents and voltages while maintaining safe operation. Integrated damping resistors reduce voltage spikes during switching, thus extending the service life of connected devices.

Product Benefits

  • Inrush Current Reduction: Precharge contacts and damping resistors eliminate the risk of excessive current peaks.
  • Safe Operation: Protects contacts from welding when switching capacitive loads.
  • High Reliability: Long lifespan even with frequent use in industrial applications.
  • Easy Installation: DIN rail mounting allows for quick integration into existing systems.
