Robertshaw RSPP6 Hard Start, 1/2 - 5 Hp, 115 to 288V, Torque 500%

The Ranco® Rocket RS Series Hard Start Kits are designed to  give your air conditioning and refrigeration units a boost! The  Ranco Rocket Hard Start Kits help protect and extend the life  of expensive compressors and components saving money and  energy. When an air conditioning or refrigeration unit turns  on, the compressor powers up to begin the cooling process.  Starting a compressor requires 4-8 times more electric  current, than running it. Over time, this jolt of power places  wear and tear on the compressor and other important  components. A hard start kit gives the compressor added  power during system start-up and reduces the amount of  electricity required. Adding a Ranco Rocket Hard Start to an  air conditioning and refrigeration system increases energy  efficiency up to 98%.
