A suppressor regulates the voltage and makes the power constant in a case of a spike or surge . A protector simply detects the surge and turns the unit off. Suppressor is good for things like computers you don't want to keep turning on and off . Like computers in a dmv or office
But terms such as protector, arrestor, suppressor, regulator, limiter, and TVSS describe devices that can perform same or completely different functions. Regulated voltage may mean light bulbs dim or brighten by as much as 50%. Each device can be so different that numbers are required to say what it really does. Even a computer's power supply could be called a suppressor and protector since it does both functions within limits.
Most often TVSS, suppressor, arrestor, SPD, limiter, and protector are different words for the same item. Those terms are too subjective to say more without details such as numbers.

FranA circuit breaker is a device that trip when current above it rated current is passing through it eg. a 5Amp breaker will trip if any current above 5amps flow throw it. A thermal overload is more like protecting the supply (cable) rather than protecting the load. its uses a thermal time constant to predict the time in which the cable will reach it maximum temperature. In this way it can give the users sometime to uses more current for a while then trip when its sees that the cable is now approaching its maximum temperature. Its take same time for a cable to reach it maximum temperature when operating on maximum current.
Circuit breaker trips on overload current.
Thermal overload trips on *overload temperature*.

What is the switch on a overload?
to protect the source from overloading a switch can be opened as a circuit breaker, fuse, overload protection schemes
Why does the surge protectors circuit breaker trip if a surge or overload is detected?
A circuit breaker shuts off the power to an electrical circuit when it detects too much current flow. As electricity moves through wiring, an electromagnetic field develops around the wire. Electromagnetic breakers capitalize on this field production by using electromagnets. The current that moves through the breaker charges the electromagnet and as the current increases the magnetic pull also increases. If the current exceeds the limit the breaker is designed to handle, the magnetic pull becomes strong enough to pull the contact plate away from the stationary plate. This breaks the circuit and is referred to as "tripping the breaker. A surge protector on the other hand prevents a voltager higher than the normal voltage from damaging electical devices. It does not shut off the power as a circuit breaker or fuse does.
Does surge strips provide a built-in 15amp circuit breaker?
If the circuit breaker is in the off position there is no need of overload protection. Overload protection monitors the load amperage, If there is no amperage through the circuit there is nothing to monitor.
Will starting current on a motor trip a gfci breaker?
A GFCI measures difference in output to return current. A Overload breaker in your panel is what trips from too much current. many are time delay and will not trip immediately from the less than a second of start up current spike.
What is the function of an LBB relay?
A local breaker backup relay is used to check the operation of distribution circuit breakers and to trip the feeder circuit breaker if the distribution circuit breaker fails to trip on an overload.
