You can still find control examples posted regarding the use of contactor control wiring implementing the O/L in the wrong part of the circuit.
For many decades the O/L in ladder circuitry has been inserted on the common or Neutral side of the coil.
This has been a no-no for some time now, but the practice still seems to exist.
It is considered a dangerous practice, especially where the common side is a ground-referenced conductor.
The diagrams shown, the O/L should be on the Left of the coil.
