The CJ19 series contactor is specifically designed for power factor correction systems, providing reliable switching of capacitor banks. Unlike standard contactors, these units mitigate the high inrush currents experienced when energizing capacitors. They employ a staged switching process: first engaging auxiliary contacts to activate current-limiting resistors, then closing the main contacts once the current is safely reduced. This protects the contacts from damage and ensures long-term operational stability. This model, CJ19-9521, is rated for 50kVAR with a 1 Normally Open (NO) and 2 Normally Closed (NC) contact configuration, operating at 220V.

The CJ19 series contactor is specifically designed for power factor correction systems, providing reliable switching of phase capacitors. Unlike standard contactors, these units mitigate the high inrush currents experienced when energizing capacitors. This is achieved through a staged switching process: auxiliary contacts first engage resistors to limit current, followed by the main contacts once the current is safely reduced. This protects the contactor from damage and ensures long-term performance.

The CJ19 series contactor is specifically designed for power factor correction systems, providing reliable switching of phase capacitors. Unlike standard contactors, these units mitigate the high inrush currents experienced when energizing capacitors – a condition that can severely stress and damage conventional switching components. They achieve this through a staged switching process, first engaging auxiliary contacts to activate current-limiting resistors, then closing the main contacts once the current is safely reduced. This protects the capacitor bank and extends contactor lifespan.

CJ19 contactors are essential components in power factor correction systems, specifically designed for switching capacitor banks. They prevent damaging inrush currents that occur when capacitors are energized, which can cause significant contact wear. These contactors utilize a staged switching process: auxiliary contacts first engage resistors to limit the initial current surge, followed by the main contacts once the current is safely reduced. This protects equipment and extends the lifespan of the capacitor bank.
