Are contactor coils present in manual motor starters?

Manual motor starters are designed to provide both overload protection and manual control of an electric motor. They typically consist of a disconnect switch and an overload relay to protect the motor from overload conditions. In manual motor starters, the operation is based on the user's direct action to start or stop the motor, which means that a contactor coil, which is an electromagnetic switch used in automatic controls, is not needed. Instead, the manual starter allows the operator to make or break the circuit directly.

Since manual motor starters do not incorporate a built-in automatic mechanism for the motor's activation, the absence of contactor coils is a defining characteristic. This distinction is crucial because it emphasizes the manual nature of the operation, contrasting those systems that utilize contactor coils for automation and remote operation, such as automatic motor starters.
