If it is tripping with nothing plugged into it, it might be shot or look for a RESET button. If it does not have one, I would not use it any more.
Surge protectors in series will limit based on twice the voltage of one surge protector because, implied by Kirchoff's Voltage Law, voltage drop across components in series is additive.Surge protectors in parallel will protect based on twice the current of one surge protector because, implied by Kirchoff's Current Law, current through parallel components is additive. (Yes, I said "protect" instead of "limit" deliberately because this is a different situation.)However, the parallel configuration is problematic because it depends on the turn-on curve of the surge protector. If one turns on first, and limits the voltage to a specific value, the other surge protector might not turn on at all. In the general case, this will not be a problem, because the turn-on curve does not have a vertical slope, but it would be advisable to consult the device specifications before contemplating this configuration.
No. If you use a larger fuse you are not protecting the device which has a rating of a lesser value.

There are 3 items that can be used for surge suppression measurements. Most of the plug in strips use Joules as a measure but this can be very misleading. Joules is a measure of energy. Energy is current (amps) times voltage (volts) times time (seconds) or E=I*V*t. Voltage during a surge is critical in determining if downstream equipment is protected. So low voltage rating are important. Current during a surge is important as this is a measure of how many amps are flowing diverting the surge from the downstream loads. So high surge current rating are important. Time is not generally critical, but is determined by the characteristics of the surge. For standard surge testing, the time is identical for the same waveshape. So Joules appears useful at first glance because it incorporates voltage and current in one measure. However, one can increase the joule rating by increasing the voltage (bad) while decreasing the current (also bad). Joules can also be manipulated by using waveforms that are not standardly used in the industry. So rather than use Joules, it is much better to look at the voltage during a surge and the maximum surge current a product uses and ensure the testing is with a recognized standard surge waveform.
a shunt coil needs external supply & tripping coil gets supply from itself.
If a surge protector had a very high resistance at all voltages, the wires in the surge protector would short out. It would kick off the protector and make it useless. A new surge protector would need to be purchased.
Reactivation of a surge protector is normally not necessary if your protector has taken a hit. Typically a protector will continue to work without the ned to reactivate it.
It will very likely damage the surge protector
a surge suppressor or protector protects your equipment from spikes on the electrical line.
A surge protector, Apex. :D
Possibly, but that's kind of missing the whole point of a surge protector. The surge protector exists to protect the things that are plugged into it. If you're not using those devices anyway during the storm, sure, go ahead and unplug the surge protector... but you could also have just unplugged the devices themselves from the wall and not bought a surge protector in the first place. Also, storms don't directly damage surge protectors. Stopping surges damages surge protectors. If there's no surge, it doesn't matter if the surge protector is plugged in or not.
The function of an APC surge protector, or any surge protector is to protect your electric goods from electrical surges. One could find more information on their website, if further information is required.
If the fuse in a surge protector is blown it will not resume operation unless the fust is replaced.
I'd be a good idea, but it isn't necessary. On the off chance that there is a power surge and the surge protector on your house doesn't work it will protect it.
I dont think it protects the system, it just keeps your computer for blowing up when there is a power surge. What the surge protector does is it takes "the hit" from the surge and that fries instead of the computer.
When looking for a quality surge protector you should consider the clamping voltage, response time, the energy absorption and dissipation rating, as well as the warranty. Two surge protector that come highly rated in those categories include the APC and Belkin Surge Protectors.
