3.Blower (squirrel cage fan) Electrical Components

a.Blower (squirrel cage fan) Controls and Overloads

1)Thermal Magnetic Starter (TMS)

The thermal magnetic starter is used as a safety device to protect the motor from starting in a locked rotor condition. The overload has a dial setting on the face of the device. To set the overload, refer to your specific electrical diagrams. The overload is specifically designed for motor applications. It has a current curve built into it so the initial high current draw by the motor will not trip the overload. On the face of the overload, there are two (2) push buttons - “START” (Black or Tan - 1) and “STOP” (Red - 0) - the overload has to be in the “START” mode for the motor to run.
