What Is a Three-Phase Surge Suppressor?
A three-phase surge suppressor is a device used to protect electrical devices from voltage spikes.
It is commonly employed to safeguard the prevalent three-phase alternating current (AC) power circuits in modern power systems. These circuits utilize three sets of alternating currents transmitted through three wires, typically colored red, white, and blue, with a phase shift to the power direction.
Installed in distribution panels or control panels, the three-phase surge suppressor functions to prevent overvoltage and overcurrent when the power is subjected to abnormal conditions such as lightning surges or other voltage spikes. This instantaneous protection helps shield equipment from damage or malfunction.
When selecting a three-phase surge suppressor, it is crucial to verify the protection levels, such as the maximum current of the equipment to be protected. Subsequently, choose a surge suppressor with an appropriate voltage withstand capability and interrupting current. Using an unsuitable suppressor may lead to the loss of protective functions.
Additionally, pay attention to the environmental conditions at the installation site to ensure optimal performance.
