    Surge Protective Devices: Know What You’re Specifying

    Surge protective devices (SPDs) are critical components of any commercial or industrial electrical system. SPDs guard equipment from the over-voltages that can result from lighting strikes or equipment operation. Without this protection, these short-term events can cause long-term – and expensive – damage. Choosing the right SPD requires knowing where the device will be applied, along with the appropriate size to meet application needs.
