The HAW562 surge protective device 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 limited or 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.

HAW562 units are primarily used in process automation and in measuring and communication technology within the water & wastewater, chemical, oil & gas as well as power & energy industry.

• Investment intensive measuring instruments protected
• Increased plant availability as surge arrester is perfectly matched to the electronic components involved in process automation and process measuring technology
• Application in Ex areas - optionally available with SIL2 intrinsically safe approvals
• Vibration and shock tested according to EN 60068-2
• Direct and indirect shield grounding
