H-R3, 5 h.p. High eff. Phase converter, For use on HEAVY starting loads, where near full Horsepower is required.(see attached webpage for hook up and Capacitor requirements.) Fuse recommendation: 25 amp. Capacitors not included. PhazPaks’ New Heavy Duty Solid State “R3” Model Converters will change the way you think about three phase motor conversion. PhazPak static converters are 100% solid state, no relay chattering, no re-generative effects on shut off, and no contacts to burn. There are many applications where single phase motors are just not available or very expensive. Consider using a high service factor three phase motor, and a PhazPak “R3” Heavy Duty Model Phase Converter system. You end up with a very efficient and reliable single phase motor. Now it is both practical and cost effective to convert your three phase motors to single phase. http://www.phazpak.com
