Us Motors C1P3B Three Phase Ac Motor 1 Hp 145T Tefc

Product Description

The US MOTORS C1P3B is a three-phase, premium efficient AC motor built for industrial and commercial applications requiring reliable continuous-duty performance. Rated at 1 HP and 1155 RPM nameplate speed, this motor operates on 230/460 volts at 60 Hz and draws 3.5/1.8 amps full load. The cast iron TEFC enclosure keeps contaminants out and suits wet, dusty, or moderately corrosive environments. Class F insulation and a 1.15 service factor give it headroom for intermittent overload conditions. A licensed electrician or mechanical contractor typically handles installation on pump, fan, or conveyor drive applications.

This motor is suited for three-phase power installations in light industrial, commercial HVAC, pump, and general equipment drive settings. The 145T frame with rigid mount configuration allows direct bolt-down to a base plate or equipment chassis. The 7/8-inch shaft diameter and 2.25-inch shaft length accommodate standard coupling and sheave arrangements common in that frame class. Reversible rotation makes it adaptable to multiple drive orientations without special ordering.

Key Features

• 1 HP output at 1155 RPM for low-speed torque applications
• Dual-voltage winding: 230/460 volts, 60 Hz for flexible power supply hookup
• Cast iron TEFC enclosure rated for harsh or outdoor environments
• 145T rigid mount frame for direct base or equipment mounting
• Class F insulation with 1.15 service factor for thermal headroom
• Reversible rotation for flexible drive configurations

Compatibility

Designed as an OEM-style replacement or new-installation three-phase motor for 145T frame rigid mount applications requiring a 1 HP, 1155 RPM, TEFC motor on 230/460-volt three-phase power.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for three-phase motor branch circuits, including proper overcurrent protection and motor disconnect means. Disconnect and lock out all power before servicing or mounting the motor. Verify that the supply voltage and phase sequence match the nameplate before energizing. Ensure the mounting base is level and rigid to prevent bearing misalignment and premature wear.
