Industrial surge protection devices help protect compatible electrical equipment from transient voltage surges. Available options support different AC and DC system requirements.
An Industrial Surge Protection Device (SPD) is an electrical protection component designed to help protect sensitive equipment and electrical systems from transient overvoltages caused by lightning-related disturbances and switching events. It works by limiting surge voltage and diverting surge current through an appropriate protective path when correctly installed.
Industrial surge protection devices are commonly used in electrical distribution panels, control cabinets, automation systems, HVAC equipment, and industrial facilities. Depending on the application, they may be designed for AC or DC circuits and offered in different voltage ratings and protection configurations.

Key Features:
Selecting the correct industrial surge protection device requires checking the system voltage, maximum continuous operating voltage, surge current rating, protection level, grounding arrangement, and installation category. Proper coordination with upstream protection and an effective grounding system are essential for reliable performance.
