Use Cases for Stearns SINPAC Motor Start Switches

SINPAC Switches are ideal for applications requiring consistent switching of the start circuit in single phase motors. Since standard mechanical switches are prone to design quality deficiencies including fatigue, contamination, corrosion, and vibration that can lead to performance inconsistencies, Stearns line of SINPAC switches help reduce production downtime for hundreds of different applications. 

Benefits of Electric Motor Start Switches

Manufactured to cut out the start circuit at approximately 80% of synchronous speed, SINPAC switches from Stearns are designed to filter out electrical noise (silent), and are cadmium free and non-sparking which increases the life of a motor. Additional advantages include:
