ELCO Capacitor Duty Contactors

ELCO Capacitor Duty Contactors

ELCO CNNK series AC-6B contactor is designed for power factor correction application.

AC6b comes with serial pre-resistor to reduce the inrush current during capacitor switching.

  • PFC sends signal to AC6b coil to close the contact
  • Serial pre-resistor will close first before main contactor.
  • After 5~10ms, Main Contact which carry the main load will close.
  • After 5~10ms, Serial pre resistor will open and Main Contact remains on close position until PFC send signal to open the contact.

ELCO Capacitor Duty Contactors

Product features

Feature pre-charging circuits to limit inrush currents, thereby minimizing wear and tear. With a high breaking capacity, they effectively manage transient currents and prevent arc restrike, ensuring reliable disconnection.

The contacts within these contactors are specially made to endure the high inrush currents common in capacitor switching, avoiding damage or welding. This makes them vital for systems where frequent, dependable capacitor engagement is crucial for maintaining energy efficiency and power quality.

Pre-Charging Circuits

These circuits significantly lower the initial inrush currents when capacitors are energized.

High Breaking Capacity

Engineered to efficiently handle and quickly quench the transient currents encountered upon disconnection.

Robust Contact Design

The contacts are specially constructed to resist the adverse impacts of high inrush currents typical of capacitor switching.
