The LiftMaster 20-3075C-4N is an OEM replacement motor engineered for select LiftMaster commercial door operators that require a 3/4 HP, 230/460V, three-phase drive. Built in a CF (C-Face) configuration for direct mounting to compatible gearboxes and operator assemblies, this motor features an NEMA 4X construction that helps protect against water ingress and corrosion, making it well suited for harsh, wet, or washdown environments such as car washes, food and beverage facilities, agriculture, and coastal installations. It restores reliable torque delivery for sectional and rolling steel overhead doors in demanding industrial and commercial applications.
This dual-voltage three-phase motor is intended for use only with LiftMaster operators specified for a 3/4 HP, C-Face, NEMA 4X motor. For best results, have a qualified technician perform installation, confirm voltage selection (230V or 460V) per the nameplate and LiftMaster service documentation, verify rotation, and ensure overload protection and controls are correctly matched to the motor’s full-load amperage. Use this genuine LiftMaster replacement part to maintain OEM performance and compatibility in commercial overhead door operator systems requiring a durable NEMA 4X C-Face motor.
