The RCCx reactive current power factor control detects reactive current in a single- or three-phase line and closes its output contacts if above the set limit. It can thus dynamically compensate low inductive power factor lines by signaling the need to switch capacitors in and out of the line. It is very simple to install and adaptable to all power factor compensation applications.
RCC3 Reactive current power factor control

RCC3 Reactive current power factor control

The RCCx measures the reactive current in a single-phase (RCC1 models) or three-phase (RCC3 models) line system and closes the 12 A output contacts when the monitored reactive current is above the preset value. The current is detected with a current transformer (CT) in one of the phase lines with a maximum response time of about 30 seconds.

The RCCx's response makes it particularly suitable for fast dynamic compensation of frequently started, low-duty or variable loads such as:

They are designed for standard European and US, single- and three-phase, 50-60 Hz lines. Characterizing features are as follows:

The relay contacts are closed when the detected reactive current is above the respective set value as determined at the activation potentiometer.

Our CACSW integrated PF capacitor AC switch interfaces directly to the RCCx output in switching and monitoring capacitor banks up to 3x25 A. Other power factor related products are summarized here with sampling/small quantities being available for online purchase here.
