Us Motors C3P1B Three Phase Ac Motor 3 Hp 182T Tefc

Product Description

The US MOTORS C3P1B is a three-phase, premium-efficient AC motor built for demanding general-purpose industrial and commercial applications. Rated at 3 horsepower and 3540 RPM nameplate speed, it operates on 230 or 460 volts at 60 Hz. The motor features a cast iron TEFC (Totally Enclosed Fan-Cooled) enclosure that protects internal components from dust, moisture, and airborne contaminants. Class F insulation and a 1.15 service factor provide a thermal margin for applications with moderate overload conditions. Full load efficiency is rated at 88.50 percent, meeting premium efficiency standards. A licensed electrician or qualified motor technician handles installation and commissioning.

This motor is suited for general-purpose applications across light industrial, commercial HVAC, pump, compressor, and conveyor installations. The 182T frame with rigid mount configuration allows direct bolt-down to a motor base or equipment frame. Reversible rotation makes it adaptable to a range of drive setups. The dual-voltage winding at 230 or 460 volts gives installers flexibility when matching the motor to available supply voltage. Single-speed operation keeps control wiring straightforward for standard across-the-line or starter-based motor control panels.

Key Features

• 3 HP output at 3540 nameplate RPM on a 182T frame
• TEFC cast iron enclosure for protection in dusty or wet environments
• Dual-voltage winding: 230 or 460 volts, 60 Hz, three-phase
• Full load amperage: 7.8 amps at 230 volts, 3.9 amps at 460 volts
• Class F insulation with 1.15 service factor for thermal headroom
• Reversible rotation and ball bearings for broad application flexibility

Compatibility

Designed as an OEM-style replacement or new-installation motor for general-purpose three-phase applications requiring a 182T rigid-mount TEFC motor at 3 HP. Also cross-references Dayton part number 5N803.

Installation Notes

Installation should be performed by a licensed electrician familiar with NEC requirements for motor branch circuits, including proper overcurrent protection, motor disconnect means, and conductor sizing. Disconnect and lock out all power sources before removing the existing motor or making any wiring connections. Verify supply voltage and phase rotation match motor nameplate ratings before energizing. Ensure the mounting base is level and rigid to prevent vibration-induced bearing wear.
