ITEM #: 4299733
Three-phase pool and spa pump AC motors don't require starting capacitors, run capacitors, or centrifugal starting switches that can wear out and fail. They operate with a higher torque and greater efficiency than split-phase pool and spa pump motors of the same HP, rpm, and frame size.
This listing is for each.
