Contactor for capacitor banks TeSys D 60kvar 3P coil 220VAC LC1DWK12M7

Capacitor bank contactor – reliable reactive power switching

This three-pole contactor from the TeSys D series by Schneider Electric, catalog number LC1DWK12M7, is specifically designed for operation with capacitor banks. It provides efficient switching of reactive power, which is crucial for maintaining a stable power factor in electrical installations. It is an indispensable element in power factor correction systems, improving energy efficiency and reducing energy costs.

Construction and application

The LC1DWK12M7 contactor is designed to control alternating current circuits with a voltage of 440V AC (50/60Hz) and a rated current of 12A. Its construction takes into account the specific requirements related to capacitive loads, including suppression of overvoltages that occur when switching capacitors. This ensures long-term and reliable operation. It finds application in power factor correction systems in industrial plants, commercial buildings, and electricity distribution networks.

Characteristics and benefits

• Designed for capacitive loads: The special design of the contactor, with built-in damping resistors, minimizes overvoltages when switching capacitors, protecting both the contactor and the capacitors themselves.
• High reliability: Mechanical endurance of 15 million switching cycles and high quality of workmanship guarantee long life and trouble-free operation of the device.
• Integrated auxiliary contacts: It has one normally closed (NC) contact and two normally open (NO) contacts, which facilitates integration with control and signaling systems. The auxiliary contacts are adapted to work with low-current signals (min. 1mA), allowing direct connection to PLCs.
• Easy mounting: Possibility of mounting on a DIN rail or on a panel facilitates installation and integration with existing systems.
• Compliance with standards: Meets the requirements of IEC 60947-1 and IEC 60947-4-1 standards, ensuring safety and compatibility with other devices.
• Wide control voltage range: A 220V AC coil allows cooperation with various control systems.
• Power factor optimization: Enables effective compensation of reactive power, which translates into reduced energy losses and lower operating costs of the electrical installation.
• High rated reactive power: Rated reactive power at 63 kvar at 400V/50Hz allows operation of capacitor banks with significant power.

The AC operating voltage is 440 V, and the reactive power at 400V/50Hz is 63 kvar. The AC control voltage is 220 V. The contactor has 3 normally closed main contacts, 2 normally open auxiliary contacts and 1 normally closed auxiliary contact. Its dimensions are: width 85 mm, height 180 mm and depth 154 mm.

The LC1DWK12M7 contactor is a solid and reliable solution for professionals involved in electrical installations and for users looking for an effective way to improve the energy efficiency of their facilities. Its specialized design guarantees safe and long-lasting operation in demanding industrial conditions.
