SMSS
The simplified motor starter can be used to reduce the starting torque of small to moderate (up to 30Hp at 480 VAC) 3-phase motors. The typical uses would be for starting air conditioning blower motors, and refrigeration compressor motors where belt drives are used. In these applications, belt slip is dramatically reduced.
