It's made to start and stop a motor safely, as well as give overload protection. In a forward/reversing motor starter, a physical barrier is moved into the path of one coil's armature by the movement of the next coil.

To connect the motor circuit in such a manner that the second motor does not start until the first one has completed its cycle, and the third motor does not run until the second one has completed its cycle, and so on. Interlocking is the term for this type of motor circuit connection.

Ladder Logic is a type of protection for motors that prevents burglary. It is also known as a ground wire system. The ladder logic rule is to wire three-conductor, rated at 250 volts and no larger than 16 amps, on the same circuit as the motor. It should be noted that Ladder Logic should not be installed if it will create a hazard or an unreasonable restriction in fire or life safety.

A characteristic that makes the status of two mechanisms or functions mutually reliant is called an interlock. It can be made up of any electrical, electronic, or mechanical components or systems, and it can be used to avoid undesirable states in a finite-state machine.

In most cases, an interlock mechanism is utilised to prevent people from being hurt or machines from being damaged. Physical controls are designed to keep hazardous energy contained, while an interlock sensor detects potentially harmful changes in condition and decreases the chance of injury or damage.
