Surge Protection Devices (SPD)


A Surge Protective Device (SPD) is a device composed of at least one non-linear component that is intended for limiting surge voltages on electrical equipment by diverting or limiting surge current and is capable of repeating these functions as specified. SPDs were previously known as Transient Voltage Surge Suppressors or Secondary Surge Arresters. UL 1449 Listed SPDs are now designated as either Type 1, Type 2 or Type 3 and are intended for use on AC power systems rated less than 1000vrms.

GE manufactures surge protection with outstanding clamping characteristics for medium and low exposure locations through the use of industrial grade MOV architecture.
