Fuses and circuit breakers are generally employed for ____________________ protection.

Auxiliary contacts are intended to control large amounts of current.

One of the main considerations when installing a machine is the power source.

The movable contact of the normally open held closed switch is drawn below the stationary contact.

Thermal overload relays trip faster when located in a cool area than in a warm area.

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).

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

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

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

Hysteresis loss is often referred to as molecular friction.
