If you have too high of a voltage for a long period of time, or too low of a voltage for a long period of time, your electronic device will blow and burn.
This is not caused by a voltage surge or impulse. This is caused by your power company that provided unregulated voltage (too much or not enough) which is pumped into your (AC) panel box. Extended Under voltage: Under voltage below 90 volts by the power company creates an over current problem. Your electronic devices are so starved for voltage and as a result, draws more current. Unfortunately your electronic devices can not handle much current and then they burn up.
Extended Over voltage: Over voltage is caused by the power company and can be up to 220 volts. If this voltage lasts for a long time, the computer chips and coils, capacitors, diodes and other electronic components will terminate. Breakermatic can monitor the voltage, and if these two problems do appear, this device will shut your power off until your voltage stabilizes.
Surge spikes and impulse are in nano-seconds. The Breakermatic does not take the place of a surge suppressor. This device is only a tool to safeguard your electronics from long periods of brown-outs and high voltage. This device works well with surge suppressors and UPS and will enhance the performance of these devices.
