FAQs
This unit is floor-mounted in a KK-sized NEMA 1 enclosure, designed for heavy-duty industrial spaces. Allow clear access for maintenance and a level, rigid floor surface to support the 1932 lb weight. Plan for integrated main breaker access and fuse protection, as well as room for wiring ducts and service clearances per local codes. Ensure compatible 600 V three-phase feeders and 60 Hz supply and allocate space for cooling airflow around the cabinet.
The 900 kVAR rating is achieved through nine discrete 100 kVAR steps, enabling fine-grained reactive power compensation. This stepping allows the system to adapt to load changes with minimal overshoot, improving voltage stability and reducing harmonic distortion. It supports smoother motor starts, better power factor, and lower energy penalties, particularly in facilities with variable production cycles and high startup currents.
Yes. The 600 V three-phase configuration and 60 Hz compatibility suit data centers with campus-scale power rails and manufacturing plants with mixed loads. Its integrated main breaker and fuse protection simplify code compliance, while the NEMA 1 enclosure provides robust protection against dust and light splashes, making it a reliable choice for critical facilities and production environments.
The unit is UL Listed and CSA Certified, signaling compliance with regional electrical safety standards. This supports regulatory acceptance and simplifies procurement for projects requiring established safety credentials. The NEMA 1 enclosure and floor-mount design are aligned with common industrial installation codes, easing integration into existing MCCs and switchgear layouts.
Maintenance is typically driven by periodic inspection of fusing, insulation, and enclosure integrity, with Eaton’s warranty coverage aiding risk management. ROI comes from improved power factor, reduced reactive charges, and enhanced equipment longevity due to steadier voltage profiles. The integrated main breaker reduces commissioning time and ongoing troubleshooting costs, supporting faster project payback.
