FAQs
The unit measures 25 in deep, 41.3 in wide, and 80 in high with a weight of 890 lb. Install on a solid, level foundation with adequate clearance for service access. Connect to a 480 V three-phase supply, include appropriate fuses, and plan for forklift-accessible placement. Ensure mounting meets enclosure and safety requirements per UL and CSA guidelines.
Key specs include a 421 A amperage rating, 60 Hz frequency, 480 V voltage rating, three-phase configuration, and a 350 kVAR rating distributed as 7 × 50 kVAR steps. The unit provides heavy-duty PF correction with fuse protection and heavy-duty capacitor cells designed for sustained industrial operation.
Yes. With 350 kVAR total correction across 7 steps, it supports PF correction for facilities with high motor loads such as injection molding, stamping, material handling, and large HVAC systems. The three-phase 480 V configuration aligns with common plant electrical architectures, enabling reliable power quality and potential energy cost reductions.
The unit is UL Listed and CSA Certified, with UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 certifications. These approvals facilitate safe electrical panel design, code compliance during audits, and streamlined integration with industrial controls, reducing commissioning risk and supporting third-party safety validations.
Warranty covers one year from installation or 18 months from shipment, whichever occurs first, reducing risk during initial operation. ROI stems from PF correction that lowers utility charges and improves process reliability—especially in facilities with persistent motor loads—leading to lower energy spend and extended equipment life.
