Contactor K3-18NK10-230V-12,50 kVAr

The K3-18NK10 contactor is designed specifically for reliable and efficient switching of capacitive loads in reactive power compensation systems. With advanced precharge contacts and damping resistors, it reduces the inrush current to less than 70 times the rated current (Ie), protecting not only the device itself but also the connected systems. This model is intended for use with low-inductance and low-loss capacitors, compliant with IEC 831 and VDE 0560 standards.

Detailed Description

The K3-18NK10 contactor is designed specifically for applications involving reactive power compensation in three-phase capacitor banks, whether equipped with reactive or non-reactive elements. Its robust construction enables efficient switching of high currents and voltages while maintaining safe operation. Integrated damping resistors reduce surge voltages during switching, thereby extending the service life of connected devices.
