Every home faces the risks of potentially damaging electrical power surges. These surges can be very brief, lasting only milliseconds, but the consequences for your household appliances can be severe.
Overvoltage may damage circuits and devices, burn wiring insulation, and potentially result in dangerous fires. Over time, even moderate voltage fluctuations can stress the delicate componentry inside computers, TVs, hi-fi, smart devices, and dozens of other household gadgets, impairing their performance and shortening their life.
A professionally fitted surge protection device, like ABB’s easy-to-install THOMESURGE and THQLSURGE SPDs, safeguards all your home electronics by safely diverting sudden voltage spikes to ground.
This prevents a dangerous build-up of electrical energy in distribution panels, devices, and systems, which can impair equipment performance, cause costly damage, or pose a fire risk.
Abrupt voltage spikes can be caused by several reasons. These include switching heavy-duty appliances on or off, overloaded electrical outlets, equipment faults, or incorrectly wired household circuitry.
Surges can also be caused by external factors, like grid issues or thunderstorms sending voltage transients through transformers and overhead power cables.
Think of a surge protection device as an electrical safety valve. During normal operation the SPD is like an open switch, allowing power to flow unimpeded. The SPD detects a sudden rise in voltage and closes almost instantaneously, creating a safe pathway to earth for the overvoltage. Once the transient has passed, the SPD re-opens automatically, and power flow continues normally.
As a leader in household power protection, ABB offers homeowners a choice of high-quality, cost-effective, and easy-to-install protection devices to safeguard home electronic appliances against surge events.
