Us Motors S3E2ACR 3 Hp Three Phase Ac Motor Tefc 182 Frame

Product Description

The US MOTORS S3E2ACR is a three-phase, premium-efficient AC motor built for demanding general equipment applications. It delivers 3 horsepower at a nameplate speed of 1765 RPM and operates on 208 to 230 volts or 460 volts at 60 Hz, making it compatible with both single and dual-voltage three-phase services. The motor uses a totally enclosed fan-cooled (TEFC) enclosure to protect internal components from dust, moisture, and airborne debris. A 182 frame size with C-Face mounting is standard. Double-shielded ball bearings and Class F insulation support continuous-duty operation in industrial and commercial settings. Licensed electricians and mechanical contractors are the primary installers.

The S3E2ACR is suited for general equipment installations where a reliable, premium-efficient three-phase motor is required. Typical applications include pumps, compressors, fans, blowers, and conveyor drives in light industrial and commercial environments. The C-Face mount allows direct coupling to gearboxes, pumps, and other flange-mounted equipment. With a 182 frame footprint and 60 Hz operation, this motor fits a wide range of standard OEM equipment bases and replacement scenarios. Full load amperage is rated at 8.5 to 7.9 amps at 208 to 230 volts and 3.9 amps at 460 volts.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Disconnect and lock out all power to the circuit before making any wiring connections. Verify supply voltage matches the motor nameplate voltage selection before energizing. Confirm the driven load is properly aligned and the mounting flange is fully seated and fastened before startup.
