Disconnect and Electric Motor Starter is used for turning the power off and on the electric motor used in HVAC applications. It also has overloads built into the starter so if one of the windings begin to pull too many amps the overloads open the circuit and the motor stops operating. Motor starters can be used for single phase and 3 phase motors and offer a manual way to turn the motor off or disconnect the electricity to the motor to prevent it from starting for maintenance or repair of the motor or peripheral systems.

The motor starter pictured above controls the starting and stopping of the motor via a relay. That is located in the bottom right corner of the photo. The relay has a red light on it, indicating it is on and running. The relay is controlled by direct digital control, which offers precision computer control of building systems, including HVAC.
Disconnect and Electric Motor Starter are generally used in commercial HVAC applications. In the photo, the motor starter is used for an air handler located in an upper-level mechanical room. The system is controlled by direct digital controls that have been integrated into the HVAC system for that building.
