• Three wire motors are a capacitor start induction run design and require a control box with a starting relay and capacitor.
• Glass filled engineered composite impellers and diffusers deliver excellent abrasion resistance.
• Use the CSCR capacitor start/capacitor run control boxes on ½ - 1 HP motors to increase efficiency and motor life and reduce energy consumption.
• The 1½ HP and larger control boxes are all CSCR type.
• Power Lead (14 AWG): Removable and replaceable motor leads are held in place by two (2) stainless steel screws for positive compression and sealing. Leads are furnished with motors and are also available as replacement parts.
