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.
