Low voltage contactors are electromechanical switching devices used to switch capacitor steps in and out of reactive power compensation systems.
Providing safe switching under steady and moderate load changes, contactors are one of the core components of compensation systems.
 

Enersolix contactor solutions meet industry requirements with pre-charge (damping) resistors designed specifically for capacitor switching and a long switching life.
 

Main Functions:

• Switching capacitor steps in and out

• Step-by-step switching to maintain the system power factor

• Working in sync with the APFC relay to control the dynamic response of the compensation system

• Protection against overcurrent, arcing and voltage surges (especially with an RC damping module)
   

Technical Specifications (Example):

• Voltage: 230 V / 400 V / 690 V

• Frequency: 50/60 Hz

• Utilisation category: AC-6b (for capacitor switching)

• Auxiliary contact configuration (NO/NC)

• Integrated RC circuit (surge suppressor)

• Long electrical and mechanical life

• Easy DIN-rail mounting
   

Applications:

• Automatic power factor correction panels

• Industrial motor control centres

• Commercial buildings and office power systems

• Detuned or reactor-equipped compensation systems

• Modules inside main distribution boards
