Fuses and circuit breakers are generally employed for ____________________ protection.

Auxiliary contacts are intended to control large amounts of current.

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

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

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).

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.

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

Hysteresis loss is often referred to as molecular friction.
