What type of device protects sensitive electronics from power surges?

A Surge Protective Device (SPD) is specifically designed to protect sensitive electronics from voltage spikes or power surges. These surges can occur due to various factors, including lightning strikes, power outages, or fluctuations from the utility company. When a surge occurs, the SPD acts to redirect or absorb the excess voltage, preventing it from reaching the connected devices and causing damage.

SPDs are essential in environments where sensitive electronics, such as computers, servers, and home theater systems, are utilized. By installing an SPD, users can significantly reduce the risk of damage to their equipment, extending the lifespan of these devices and maintaining their functionality.

Other devices, such as fuse boxes, circuit breakers, and dimmer switches, serve different purposes. While fuse boxes and circuit breakers are used for overload protection and circuit control, they do not specifically address voltage surges. Dimmer switches are designed to regulate the brightness of lights and do not provide surge protection. Thus, the SPD is the optimal choice for safeguarding sensitive electronics against power surges.
