Us Motors T2S1AH 2 Hp 3450 Rpm Tefc Three Phase Ac Motor

Product Description

The US MOTORS T2S1AH is a three-phase, energy-efficient AC motor built for general-purpose industrial and commercial applications. Rated at 2 horsepower and 3450 RPM, it runs on 60 Hz power and delivers a full-load efficiency of 77.00 percent with a service factor of 1.15. The motor uses a TEFC (Totally Enclosed Fan-Cooled) enclosure, which keeps contaminants out of the motor housing and makes it suitable for dusty or wet environments. It mounts via a rigid base on a 56H frame and features reversible rotation, giving installers flexibility during setup. Ball bearings and Class B insulation round out the construction for reliable continuous-duty operation.

This motor is suited for general-purpose applications in light industrial, commercial, and agricultural settings where a compact, two-horsepower three-phase motor is required. The 56H frame is a common industry-standard footprint, making it a practical direct-drive or belt-drive replacement in pump, fan, compressor, and conveyor installations. Single-speed operation at 3450 RPM covers a wide range of high-speed load requirements. Electricians and millwrights typically handle installation in facilities with three-phase service.

Key Features

• 2 HP output at 3450 RPM for high-speed general-purpose loads
• TEFC enclosure resists dust, moisture, and debris ingress
• 56H rigid-mount frame for straightforward mechanical alignment
• Reversible rotation for flexible installation orientation
• 1.15 service factor allows brief overload operation above nameplate rating
• Class B insulation rated for continuous-duty performance

Compatibility

Designed as an OEM-style replacement or new-install option for general-purpose three-phase applications requiring a 2 HP, 56H frame, TEFC rigid-mount motor. Cross-references Dayton part number 3N445.

Installation Notes

Installation should be performed by a licensed electrician or qualified millwright familiar with three-phase motor wiring and NEC requirements. Disconnect and lockout all power before handling the motor or making electrical connections. Verify shaft alignment and belt tension before startup to avoid premature bearing wear. Ambient operating temperature is rated to 40 degrees F minimum; ensure installation location meets this requirement.
