FAQs
Ensure adequate clearance for ventilation and service access around the 1200 lb unit, and verify mounting with compatible frame 943 enclosures. Plan for proper wiring to 283B terminals and confirm grounding per local electrical codes. Pre‑assembly of primary and secondary cables minimizes on‑site disruption and reduces commissioning time.
DOE2016 Efficient certification indicates enhanced core/coil efficiency and reduced I2R losses, translating to lower standby and load‑driven energy consumption. In practice this reduces heat generation in enclosures, lowers cooling requirements, and can shorten payback periods for energy‑intensive applications such as motor drives and CNC equipment.
Yes. With 150 kVA, three‑phase operation and a 480 V to 208Y/120 V output, it accommodates common automation loads and drives. The K‑Factor nonlinear design minimizes harmonic distortion, protecting sensitive electronics and improving overall panel reliability in modern production environments.
Key certifications include UL Listed safety and DOE2016 Efficient energy performance. These credentials support compliance with electrical safety standards and energy targets in manufacturing plants, data centers, and automation facilities, reducing procurement risk and easing inspector reviews.
Schedule regular visual inspections, monitor temperature rise and cooling performance, and verify connection integrity at the 283B terminals. Use proper enclosure ventilation and periodic insulation checks. Selecting the DOE2016 efficient model reduces ongoing energy costs, while UL Listed assurance lowers risk and downtime, boosting long‑term ROI.
