High-Performance NEMA 3R Variable Frequency Drives (VFDs) for Industrial Applications
Our NEMA 3R-rated Variable Frequency Drives (VFDs) are engineered to provide reliable motor control for a wide range of industrial applications. Designed for use in demanding environments, these drives ensure optimal performance, energy efficiency, and precise motor speed control in HVAC, water treatment, manufacturing, and other heavy-duty industries.
Available in 208V, 230V, and 460V configurations, these VFDs are designed to handle power outputs ranging from 0.75 HP to 150 HP, making them versatile solutions for small to large-scale applications. The units come with various bypass options, including:
✔ NEMA 3R Fused Disconnect – Ensures safe and efficient power isolation.
✔ NEMA 3R 2-Contactor Bypass – Provides motor bypass functionality while maintaining system reliability.
✔ NEMA 3R 3-Contactor Bypass – Offers additional control redundancy for critical applications.
✔ NEMA 3R 3-Contactor Bypass with Auto-Bypass – Ensures seamless operation by automatically switching to bypass mode if needed.
Each unit features robust construction with a NEMA 3R enclosure, ensuring protection against dust, rain, and environmental contaminants. Whether you require precise motor speed control, smooth start-up functions, or fail-safe bypass options, our VFDs provide the performance, reliability, and flexibility your operation needs.
