Joules is a unit of energy. The rating says how much energy they can absorb in a surge without being damaged. If damaged by a surge you better just throw it out.
In joules
Depends on a type of protector. Some protectors work by absorbing energy. These might be rated in joules (pronounced 'jewel'). Are typically hundreds or a few thousand joules. Another protector for all types of surges works differently. It is measured in amps. For example a typically destructive surge (lightning is one example) might be 20,000 amps. So a 'whole house' protector is minimally 50,000 amps. Protector must not stop working. If properly sized, it only degrades. Protector that is grossly undersized stops working in a manner that violated the manufacturer's specifications. And that is a potential fire. A typically destructive surge can be hundred of thousands of joules. What does that do to the first type protector that must somehow absorb that energy? Two type protectors. One rated in joules. The other in amps.
Yes, it is highly recommended to use surge protectors for computers to safeguard against power surges and fluctuations that can damage sensitive electronic components. Surge protectors help protect your computer from electrical spikes and ensure its longevity and reliability.
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.
Destructive surges can be hundreds of thousands of joules. A protector rated for hundreds of joules does not claim to protect from the other and typically destructive surge. In fact, a 250 joule surge will simply be converted by electronics into low voltage DC to safely power its semiconductors. A destructive surge may be 20,000 amps. So a minimal 'whole house' protector for all homes should be at least 50,000 amps. Any protector that fails on a surge did not provide effective protection. And was a potential house fire.

Surge protectors vary in price depending on how big you need one to be. Some surge protectors even come with guarentee's that they will not ruin your electronics. Surge protectors run from $10 to $30.
There are three main types of surge protectors available in the market: power strip surge protectors, wall outlet surge protectors, and whole-house surge protectors. Power strip surge protectors are portable and provide multiple outlets for devices. Wall outlet surge protectors are installed directly into the wall outlet for a more permanent solution. Whole-house surge protectors are installed at the main electrical panel to protect the entire home from power surges.

For protectors adjacent to appliances, a shunt type connects energy to other wires. A series type blocks by filtering and absorbing energy. These protectors are rated by the amount of energy it can absorb - joules. A ballpark measure of its life expectancy. Those protectors are completely different from another type that must be located elsewhere. These other protectors perform differently and protect from other types of surges that more often do damage. These are often rated in terms of current - amps. A ballpark measure of its life expectancy.
There are many online shops that sell best surge protectors. Amazon.com is one of online shop that sells best surge protectors with any kind of models and specifications. You can visit www.amazon.com
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.
Yes, the surge protectors circuit breakers can be reset an unlimited number of times.

Not really. They might help a little, but they are not surge protectors
Surge protectors divert excess voltage from power surges away from electronic devices, preventing damage to them.
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.
