What device is used to bypass and discharge electrical surges?

The device that is specifically designed to bypass and discharge electrical surges is a surge protector. Surge protectors are essential in protecting electronic devices from voltage spikes that can occur due to lightning strikes, power outages, or other disruptions in the electrical supply. They work by redirecting excess voltage away from the device, thereby preventing damage.

Surge protectors typically contain components like metal oxide varistors (MOVs) that act as a short circuit during a surge, allowing the excess voltage to be diverted safely to the ground. This function is critical because it ensures that sensitive electronics, which can be easily damaged by voltage spikes, remain safe.

In contrast, devices like circuit breakers and fuses serve a different purpose. They are primarily protective devices that interrupt the flow of electricity in the event of an overload or short circuit to prevent overheating and potential fires. Voltage regulators, on the other hand, maintain a consistent voltage level to devices but do not necessarily provide protection against surges. Each of these devices plays an important role in safeguarding electrical systems, but when it comes to specifically managing electrical surges, the surge protector is the key component.
