Us Motors C5P1B 5 Hp Three Phase Tefc Ac Motor 184T

Product Description

The US MOTORS C5P1B is a three-phase, premium efficient AC motor rated at 5 horsepower and designed for continuous-duty industrial and commercial applications. Built with a cast iron frame in NEMA 184T configuration, it operates at a nameplate speed of 3515 RPM on 60 Hz power. The TEFC enclosure protects internal windings from dust, moisture, and contaminants, making it well suited for demanding environments. Full load efficiency is rated at 89.50 percent, and the Class F insulation supports a service factor of 1.15. At 110 pounds, this is a heavy-duty motor intended for permanent installation by a licensed electrician or qualified mechanical contractor.

The C5P1B is a general-purpose motor applicable across a wide range of industrial, commercial, and agricultural drive systems. Rigid mount configuration fits standard 184T frame bases and adapters. Reversible rotation allows flexibility in drive configuration during installation. The single-speed design, ball bearing construction, and robust cast iron frame make it appropriate for pump drives, compressor drives, conveyor systems, and similar fixed-load applications where consistent output and long service life are priorities.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NEC requirements for motor branch circuits, including proper disconnect, overcurrent protection, and grounding. Disconnect and lock out all power before mounting or making any wiring connections. Verify supply voltage and phase configuration match motor nameplate ratings before energizing. Confirm base alignment and coupling or belt tension per the drive system manufacturer guidelines to avoid premature bearing wear.
