ENDRESS+HAUSER HAW569-DA2B Line Protector, 5 kA, Panel, HAW569 Series

HAW569-DA2B is a surge arrester. It is used to weaken residual currents from upstream lightning protection steps and to limit system-induced or system-generated overvoltage surges. This HAW569 unit is primarily used in process-related instrumentation within the chemicals, pharmaceuticals, and oil and gas industries as well as in the water and wastewater sectors. It is used to protect electronic components in field devices from being destroyed. It ensures that overvoltage surges that occur in signal cables (e.g. 4 to 20mA), in communication lines of field buses (HART, PA, FF), and in power lines are safely passed into the ground. The functionality of the electronic component to be protected is not affected as, using the impedance-free connection of the protection unit, interference voltage drops cannot be introduced.
