ENDRESS+HAUSER HAW562-AAB Surge Protector, Surge Arrester, 2 Pole, Type 3, 2 kA, 75 VDC, DIN Rail

HAW562-AAB is a surge arrester. This surge arrester is used to weaken residual currents from upstream lightning protection steps and to limit system-induced or system-generated overvoltage surges. HAW562 units are primarily used in process automation and in measuring and communication technology within the chemicals, pharmaceuticals, water and wastewater sectors as well as in the food industry. It is used to protect electronic components from being destroyed by overvoltage. It ensures that overvoltage surges that occur in signal cables (e.g. 4 to 20mA), in communication lines (field buses) and in power lines are safely passed into the ground. The functionality of the transmitter or the electronics component to be protected is not affected. Increased plant availability as a surge arrester is perfectly matched to the electronic components involved in process automation and process measuring technology.
