Contactor for capacitor banks Q=20 DILK20-11(230V50HZ,240V60HZ) 294010

Contactor for capacitor banks – reliable connection and power factor correction

This contactor, designated DILK20-11(230V50HZ,240V60HZ), is a key component in central reactive power compensation systems. Designed to work with capacitor banks, it provides efficient connection and disconnection of circuits, minimizing energy losses and improving power quality. It is a solution for both professional installers and end-users looking to optimize energy consumption.

Application and functionality

This contactor is designed for use in compensation systems with inrush currents of up to 180 times the rated value. The capacitors are pre-charged using leading auxiliary contacts and resistors, which effectively limits the inrush current – protecting both the contactor and the rest of the installation. This ensures that the capacitor switching process is smooth and safe.

Construction and parameters

The DILK20-11 contactor is characterized by a solid construction and high reliability. It has three main normally open contacts and one auxiliary normally open and one normally closed contact. The connection of the main contacts is made using screw connections, which ensures a secure and durable connection of the wires. It is designed to operate in AC networks with a voltage of 230V to 690V (50Hz and 60Hz), and the control voltage is 230V (50Hz) and 240V (60Hz) respectively. The rated reactive power for a voltage of 400V is 20 kvar, and the rated switching current is 29A. Compact dimensions (45 mm wide, 135 mm high and 138 mm deep) make it easy to install even in limited spaces.

Advantages for the installer and user:

• Limitation of inrush currents: Pre-charging the capacitors minimizes the risk of damage and extends the life of the equipment.
• Voltage versatility: The ability to operate in networks with different voltages (230…690 V AC) increases application flexibility.
• Safety: Solid construction and precise contacts ensure reliable operation for a long time.
• Easy installation: Screw connections facilitate quick and secure connection of wires.
• Compact dimensions: Allow installation in tight spaces without loss of functionality.
• Energy efficiency: By compensating for reactive power, it contributes to lowering electricity bills.
