What is the duty cycle SINPAC® switches can operate at?

This is dependent on actual switch used, current draw, ambient temperature, and time the switch is engaged - e.g., 3S or 1/2S. CV and VR switches have been tested at 2-3 cycles per minute under normal conditions. IR switches have been tested at 1 cycle per minute under normal conditions.

Why won't my SINPAC® switch work with my motor?

Reference the Stearns SINPAC® catalog, and assure that the proper switch has been selected based on Motor Horsepower, Motor Start Circuit voltage, full load motor amps, and proper cut-out voltage.
