Endress+Hauser Single Phase Surge Arrester, 10kA, 650V (Volts), Screw Mount Mount

The Endress+Hauser HAW569 surge arrester for field mounting is used to protect electronic components in field devices from being destroyed by overvoltage. It ensures that overvoltage surges which occur in signal cables (e.g. 4 to 20 mA), 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 is not affected thanks to the impedance-free connection of the protection unit.
