Applications
• Use on any single phase air conditioner or refrigeration unit
• Low voltage situations
• Hard starting compressors
Choosing the correct hard start for the application combines a technical need with a professional preference. Select from the broadest offering of hard
starts from the Pioneer of Hard Start technology.
Three (3) styles to choose from:
• SPP Series PTC/Capacitor combination
• SPPE Elite Series Electronic Potential Relay (EPR)/Capacitor combination
• SK3W Series 3-wire Potential Relay/Capacitor combination
