FAQs
Plan for a sturdy mounting surface, proper clearances for heat dissipation, and space for wiring access to the main breaker and fuses. Ensure compatibility with a 480V three-phase system and confirm outdoor or indoor placement aligns with the NEMA 3R enclosure requirements. Verify panel ambient temperature ratings and allow for expansion if additional 50 kVAR steps are desired in the future.
Yes. The unit is specifically rated for 480V three-phase operation with a 60 Hz frequency, 662A amperage, and a 550 kVAR total PF correction capacity distributed across 11 x 50 kVAR steps, making it compatible with common industrial power distribution architectures.
It is UL Listed and CSA Certified, with compliance to UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18, ensuring electrical safety, control panel compatibility, and performance reliability in regulated environments.
The 11Ă—50 kVAR stepping allows staged PF correction that adapts to load fluctuations, reducing overshoot and minimizing capacitor switching stress. This translates to faster payback, reduced utility penalties, and better voltage regulation for motor loads and drives.
