GPZ532 is a gas-filled surge protector designed by ProTek Devices that is used to protect sensitive electronic equipment from damaging surges, transients and high-energy pulses. It is a simple, robust device that consists of two conductors sealed within an epoxy glass body filled with SF6 non-flammable, dielectric gas. The conductors are connected together and terminate in terminations, allowing a voltage to pass through the device. The device is designed to absorb large power surges and provide high-level protection against transients, high-current pulses, and spikes. It is suitable for use in a wide range of applications, including telecommunications, industrial, automotive, medical, and consumer electronics.
