The ATVMaster 1.5 HP Single-Speed Replacement Pool Pump Motor is engineered with a standard 48Y Square Flange and precision-machined 1045 carbon steel threaded shaft[cite: 31, 35, 36]. Designed as a direct replacement for Century / A.O. Smith models USQ1152, EUSQ1152, and ASQ165 (also cross-referencing B854, B858, and B2854), this motor delivers water circulation for in-ground pools, spas, and water features[cite: 34, 36]. Operating at 3450 RPM, it features dual-voltage capability (115V / 230V) for standard field wiring setups, continuous duty rating, and integrated CET-50-ABM thermal overload protection[cite: 31, 35, 36].
COMPATIBILITY & FITMENT
