- Accurate and reliable power factor control of a system even in presence of high current and voltage harmonic content
- Warrants optimal capacitor use for increased life using rational control of the capacitor operation and connection time
- RMS voltage and current measure
- Measure of average weekly power factor (last 7 days), capacitor overload, electric panel temperature, voltage and current harmonic content
- Event viewing when harmonic overload limit exceeded
- Harmonic content analysis of logged events complete with relative waveforms
- Adjustable tripping sensitivity, integral switching time
- Adjustable reconnection time delay (DCRJ8-DCRJ12)
- No-voltage release protection
