it cant protect the system against power surges
The best protection is a good UPS (Uninterruptible Power Supply). That will protect you against both surges and brown outs, as well as allowing you to power down safely in case of a power outage.

Short circuits.
An electrical device used to protect electronic devices against power fluctuations against power surges by tripping or blowing before those devices can be damaged. They are a very low cost insurance policy built in to equipment to protect it against costly damage.

Yes it can. In fact, if your computer and modem are both plugged into an UPS you may be able to continue surfing during a power outage. It will also protect the modem from power line surges and brown outs that could otherwise be destructive. Many UPS have jacks to plug the telephone line in to protect against surges on the telephone line (phone modems) but typically don't have protection for surges on cable.
Kensington SmartSockets basic adapter provides protection against power surges. It has eight color coded sockets to easily track your cords, and also has a $25,000 limited connected equipment warranty.
Surge protectors are primarily designed to protect electronic devices from power surges and spikes. While they may help reduce the risk of electrical fires by preventing power surges that could potentially lead to overheating, they are not a guaranteed protection against all causes of electrical fires. It is important to follow proper electrical safety practices and consider using additional fire prevention measures.
Printers do not require power surge protection is an example of a false statement about protecting against power surges. Lightning can cause a power surge.
Surge protectors are devices that protect systems against lightning strikes by diverting excess voltage to the ground. However, surge protectors are not designed to protect against sags and brownouts, which are characterized by a decrease in voltage levels. To safeguard against sags and brownouts, a UPS (Uninterruptible Power Supply) or voltage regulator may be necessary.
Surge protectors are used to protect electrical devices and appliances from voltage spikes or surges caused by fluctuations in the electrical supply. These surges can be caused by lightning strikes, power outages, or grid disturbances, and can damage or destroy electronics and other sensitive equipment in a home.
