Why the GP30/60NL DualZone Phase Converter
Intelligent load sensing automatically switches between 30 HP and 60 HP zones. Run small tools at lower capacity, heavy equipment at full power — all automatically.
Clean, balanced three-phase power in both zones. Won't damage sensitive equipment or trip breakers under load.
When running smaller loads, the system operates in the lower zone — using less energy than a single large converter running at partial capacity.
Thermal and magnetic protection in both zones. AutoLink soft-start prevents inrush damage on startup.
Continuous duty rated. TEFC motors handle 24/7 operation in demanding environments — dust, heat, and vibration.
One converter covers a wide range of applications. Perfect for shops that mix small and large three-phase equipment throughout the day.
IP65 Weatherproof Control Panel
Every panel is rated IP65 — fully sealed against dust and water jets. Install indoors or outdoors with confidence, even in harsh shop environments.
Heavy-Duty TEFC Idler Motors
Totally Enclosed Fan Cooled motors with cast iron frames, precision-balanced rotors, and sealed bearings. Built for decades of continuous industrial service.

Talk to an engineer — we'll size the right DualZone phase converter for your exact setup
The GP30/60NL is a dual-capacity auto-zoned rotary phase converter designed and manufactured by Phoenix Phase Converters in Phoenix, Arizona. This innovative phase converter provides two power zones — 30 HP and 60 HP — with automatic switching between them based on your connected load. When you're running smaller equipment, the converter operates in the efficient 30 HP zone. When heavy-duty machinery kicks in, it automatically scales to the full 60 HP zone.
The DualZone design is perfect for shops and facilities that run a variety of three-phase equipment sizes. Instead of oversizing a single converter or running two separate units, the GP30/60NL intelligently adapts to your load requirements in real time.
