The HAW562 surge arrester 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.
Voordelen

Toepassingsgebied
Surge arresters are used to weaken residual currents from upstream lightning protection steps and to limit system-induced or -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.
