Automatic switching with a two-stage control delivers real-time VAR optimization. This reduces demand charges, improves power factor, and minimizes manual intervention in daily operations. Applications include large industrial facilities with variable motor loads on 4160V, 60 Hz systems. 956 kVAR capacity at 4160V provides scalable reactive support that aligns with changing production needs. The 4.2H detuned filter suppresses harmonic interactions, protecting feeders and transformers from voltage spikes and overheating. Two-stage design enables finer control across load swings, delivering smoother voltage profiles for sensitive equipment. Applications span manufacturing, mining, and processing facilities where consistent VAR management translates to higher uptime and lower operating costs.

FAQs
This unit weighs about 12,020 lb and measures roughly 49 in long, 91 in high by 225 in wide, requiring a structurally sound dedicated equipment room with adequate clearance for service access and ventilation. Plan for a reinforced floor, rigging capabilities for lifting, and appropriate clearances around utility connections for safe installation and future maintenance.
Key specs include 956 kVAR at 4160V, 60 Hz operation, a two-stage configuration, and a 4.2H detuned filter. The two-stage AutoVAR control dynamically injects or withdraws VAR to maintain target power factor and voltage, reducing strikes in voltage fluctuation and improving overall system efficiency with minimal manual intervention.
Yes, the 4.2H detuned filter is designed to mitigate harmonic resonance and interactions with feeders, protecting transformers and motors. The combination of detuned filtering and automatic VAR control helps stabilize voltages in environments with variable motor loads and harmonic-rich equipment, enhancing reliability for sensitive loads such as drives and PLC-controlled processes.
The unit carries IEEE Std. 18 compliance and CSA certification (Canada). These certifications support regulatory alignment for Canadian projects and provide a credible basis for international deployments where IEEE/CSA standards are recognized, helping procurement teams meet power quality and safety requirements across facilities.
Warranty terms follow Eaton policy: one year from installation or eighteen months from shipment, whichever occurs first. ROI comes from improved power factor, reduced energy penalties, and lowered manual switching costs, plus longer equipment life due to stabilized voltage and harmonics, supporting predictable maintenance planning and lower total cost of ownership.
