One common use for the normally open set of contacts on an overload relay is to provide an input signal to a programmable logic controller (PLC).

____________________-automatic switches are generally used to select the function of a motor controller either manually or automatically.

Motor starters are basically a contactor and overload relay mounted together. Most do not need auxiliary contacts. 

Normally open switches are drawn with the movable contact above and touching the stationary contact.

Hysteresis loss is often referred to as molecular friction.

The current flow through the MOV is called ____________________ current and is so small that it does not affect the operation of the circuit.

Motor starting current is referred to as ____________________ current.

Control transformers are generally protected by fuses or ____________________.

____________________ switches are drawn by adding a wedge to one of the four basic switches.

Manual control may be accomplished by simply connecting a switch in series with the motor.
