A. O. Smith Continues to Expand 4-in-1® Line

A. O. Smith Electrical Products Company has expanded its popular line of 4-in-1® multiple-horsepower motors to now include new ½ horsepower ratings. The new 4-in-1 motors replace hundreds of the most popular 1/2-1/5 horsepowers, 208-230 and 460 volts, 825 or 1075 RPM residential and commercial condenser fan motors.

The expanded line includes three new ½ horsepower ratings for the deluxe 4-in-1 HeatMaster® motor series for use in high ambient temperature applications. With this new horsepower option, the 4-in-1 line now reduces the need to stock four different models for replacement applications.

The exclusive HeatMaster line of motors is built with UL and CSA approved Class F insulation, which enables these motors to meet 70°C (158°F) maximum ambient temperatures. In addition, the ultra high-torque designs and the use of double sealed ball bearings allow the 4-in-1 HeatMaster motors to perform in even the toughest applications.

A. O. Smith’s 4-in-1 motors may be mounted by bellyband, thru-bolts or shell holes; and the totally enclosed construction of the motor allows for all-angle mounting and are designed with a water-resistant reversing plug for quick rotation change.

These 48-frame condenser fan motors are installed with one simple connection, eliminating complicated wiring diagrams and the need to switch capacitors – features that make installation much easier for contractors.

Whether the contractor carries the original economy line or the deluxe line of multi-horsepower replacement motors, each model is designated with the A. O. Smith Conservationist™ logo symbolizing its high efficiency rating.
