Endress+Hauser Single Phase Surge Arrester, 9kA, 550V (Volts), DIN Rail Mount

The Endress+Hauser HAW562 surge arrester for DIN rail is used to protect electronic components from being destroyed by overvoltage. It ensures that overvoltage surges which occur in signal cables (e.g. 4 to 20 mA), in communication lines (fieldbuses) 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. Surge arresters are used to weaken residual currents from upstream lightning protection steps and to limit system-induced or -generated overvoltage surges.
