Contactor for capacitor bank Q=50 DILK50-10(230V50HZ,240V60HZ) 294076

Contactor for capacitor banks – effective reactive power compensation

This three-pole DILK50-10 contactor from Eaton is designed to switch capacitor banks in central reactive power compensation installations. Its design takes into account the specifics of working with inductive loads, such as capacitors, ensuring reliable and safe operation. The device is particularly useful in applications requiring reactive power compensation with 180-fold inrush current peaks.

Application and functionality

This contactor is used in power factor correction (cos φ) systems in industrial and commercial installations. By effectively switching capacitors, it minimizes energy losses, reduces operating costs, and improves power quality. Pre-charging the capacitors via leading auxiliary contacts and resistance wires limits the inrush current, protecting the contactor and extending its service life.

Design features and operating parameters

The device is characterized by a solid construction and high quality of workmanship. It has three main normally open contacts, which allows for effective switching of the load. It is designed to operate in AC networks with a voltage of 230…690 V (50 Hz) or 240…690 V (60 Hz). The rated reactive power is 50 kvar for both 50 Hz and 60 Hz frequencies. The connection of the main contacts is made using screw connections, which ensures a secure and durable electrical connection. Compact dimensions (55 mm width, 190 mm height and 147 mm depth) facilitate mounting in electrical switchboards. An additional normally closed auxiliary contact increases the control and signaling capabilities of the device.

• Energy cost optimization: By compensating for reactive power, it reduces the demand for active power, which translates into lower electricity bills.

• Increased system efficiency: Improving the power factor allows for better utilization of the available power in the network, increasing the efficiency of electrical devices.

• Installation protection: Limiting the inrush current protects the contactor and other elements of the installation from damage caused by overvoltage.

• Reliable operation: Solid construction and high-quality components ensure long-lasting and trouble-free operation of the device.

• Easy installation: Compact dimensions and screw connections facilitate the installation of the contactor in an electrical switchboard.
