Contactor for capacitor banks Q=12.5 DILK12-11(230V50HZ,240V60HZ) 293988

Contactor for capacitor banks – effective reactive power compensation

This three-pole DILK12-11 contactor from Eaton, with a power of 12.5 kvar, is designed for connection in central reactive power compensation installations. Its construction allows for effective use in systems with high inrush current peaks, reaching 180 times the rated current. This contactor is particularly useful where reliable protection and control of capacitor banks are required.

Construction and application

The DILK12-11 contactor was designed to work with capacitors equipped with pre-charging resistors. This solution minimizes inrush currents during switching, protecting both the contactor and the rest of the installation. This allows for smooth and safe switching of the capacitive load. A wide range of operating voltages (230…690 V AC for 50 and 60 Hz) makes it a universal solution for various industrial and commercial applications.

Key features and benefits

• High reliability: The construction based on proven Eaton components guarantees long-term and trouble-free operation.
• Limitation of inrush currents: Pre-charging of capacitors through leading auxiliary contacts and resistance wires minimizes stress on the installation during switching. This translates to a longer lifespan of devices and a lower risk of failure.
• Voltage universality: The ability to operate in both 50 Hz and 60 Hz networks and a wide range of operating voltages (230…690 V AC) ensures application flexibility.
• Compact dimensions: Dimensions of 45 x 135 x 138 mm allow for easy integration of the contactor into existing installations, even in limited spaces.
• Contact configuration: It has three normally open main contacts (3NO) and one normally open auxiliary contact (1R) and one normally closed (1Z), which allows for the implementation of various control and signaling functions.
• Screw connection: Ensures a solid and durable connection of wires, minimizing the risk of loosening connections during operation.

This contactor is a solid choice for both professional installers looking for a reliable component for reactive power compensation systems and end-users who want to improve the energy efficiency of their electrical installations.
