FAQs
The capacitor bank is designed for three-phase 480 V systems and fits typical LV switchgear setups. It uses a NEMA 3R enclosure with fuses and heavy-duty capacitor cells, supporting outdoor or rugged-area installations. It can be integrated alongside standard LV equipment in facilities with motor loads and drives, provided the enclosure and connection clearances meet local codes.
It automates power-factor correction by supplying reactive power as loads vary, reducing reactive energy and PF penalties. The result is lower energy costs, steadier voltage profiles, and reduced stress on motors and drives, improving overall equipment efficiency and extending asset life in continuous production environments.
Yes. The unit uses a NEMA 3R enclosure and heavy-duty capacitor cells, making it appropriate for outdoor or harsh environments. Protective fusing and enclosure design support weather resistance and safe operation, reducing the need for indoor space and enabling placement near external switchgear where reactive power is generated.
The capacitor bank is CSA Certified and UL Listed, with UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 certifications. These credentials support electrical safety, performance reliability, and regulatory compliance in many industrial markets and data centers.
With an 8 x 50 kvar configuration (400 kvar total) and automatic PF control, facilities typically see reduced utility penalties and energy costs, delivering faster ROI. The solution includes a one-year warranty from installation (or 18 months from shipment) and standard maintenance considerations centered on periodic inspection of fuses and capacitor banks to sustain performance.
