FAQs
The unit is floor-mounted in a 3‑phase 480 V system with a KK+KK frame and a NEMA 1 enclosure. Plan for adequate floor space, access for wiring and breakers, and alignment with existing switchgear. Ensure compatibility with molded-case breakers rated 65 kAIC and proper clearance for maintenance access.
It automatically tunes reactive power via 9 x 100 kVAR steps (900 kVAR total) and 4.2H tuning, reducing VAR demand, lowering current, and stabilizing voltage. This results in fewer utility penalties, improved motor efficiency, and enhanced system reliability without frequent manual intervention.
Yes. The filter is designed to integrate with molded-case circuit breakers rated at 65 kAIC, enabling proper coordination and protection. This compatibility supports straightforward retrofits and ensures safe, orderly fault isolation within standard plant distributions.
The unit carries UL Listed and CSA Certified markings, confirming compliance with recognized electrical safety standards. While not listed here, verify any additional regional requirements (such as CE or IP ratings) for your specific project scope and facility.
ROI comes from reduced reactive power charges, lower line current, and improved equipment efficiency. While exact payback varies by site load profile and tariff, the automatic control, high-capacity 900 kVAR bank, and durable on-floor installation typically yield measurable annual savings and quicker procurement cycles through certified safety and compatibility.
