20 HP rotary phase converter with PL controls.
The GP20PL converts 230V single-phase utility power into 230V three-phase power for shops and facilities that need a 20 HP rotary phase converter with pushbutton operation and built-in voltage monitoring.
Need compressor, HVAC, chiller, or paired equipment operation? Ask for the AutoLink version so the SKU and controls match the load.
Running capacity 20 HP
Largest motor 10 HP
Input 230V 1-phase
Output 230V 3-phase
Description
Built for practical three-phase power in a single-phase shop.
The GP20PL is the premium 20 HP Phoenix rotary phase converter package for customers who want pushbutton control and a visible voltage monitor at the electrical panel. It is a strong fit for machine shops, woodworking shops, farm buildings, and industrial work areas with 230V single-phase service.
For ordinary shop loads, the GP20PL gives a clean way to run three-phase equipment without waiting on a utility three-phase service upgrade. For compressors or HVAC-style loads, use the AutoLink option instead of a bare PL model.

Why GP20PL
When visibility at the panel matters.
Pushbutton operation
Start and stop controls are built into the panel, which makes daily use simpler in busy shop environments.
Continuous-duty idler
The TEFC idler motor is built for industrial environments where dust, heat, and daily use are normal.
Supportable wiring
Labeled terminals, published manuals, and Phoenix support make the installation easier to verify.
Applications
Common uses for a 20 HP PL converter.
Use the GP20PL where the largest starting motor is within the supported range and the total running load fits the 20 HP converter rating.
