air compressor motor
Is your installation at a residence? at a business? do you have three phase power available? What follows is a connection diagram of a three phase magnetic starter on a three phase line. The motor will need three overload heaters for the magnetic starter. take the nameplate current and look on the cover of the magnetic. you will see a range of amperages. get three overloads as close to the nameplate current without going excessively over. This is to protect your motor should there be a bad bearing or something that might slow your motor down without burning up the motor. this magnetic is used at line voltages so be careful. most industrial starters now used - use a separate control circuit at either 24 volts or 120 volts ac.
