Simple, Labeled Installation
Every terminal is clearly marked — T1 and T2 for your single-phase 230V input. No guessing, no electrician headaches. Connect your single-phase supply and you're running three-phase power.
Why the GP100NL Phase Converter
Clean, balanced three-phase power from your single-phase supply. Won't damage sensitive equipment or trip breakers under load.
One phase converter powers your entire shop — up to 100 HP of simultaneous three-phase load across all your equipment.
Thermal and magnetic protection safeguards your equipment. AutoLink start system prevents inrush damage on startup.
Continuous duty rated. TEFC motor handles 24/7 operation in demanding environments — dust, heat, and vibration.
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 Motor
Totally Enclosed Fan Cooled motor with cast iron frame, precision-balanced rotor, and sealed bearings. Built for decades of continuous industrial service.
🏗️ Common Applications for 100 HP Phase Converters
