Class IEC 2 surge arrester HAW562

class IEC 4class IEC 3class IEC 5

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. 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. Benefits 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 Specifications Function Surge arrester for DIN rail mounting Compact device for an easy ordering (no separation of mounting module and protection module) Flexible integration into the measuring chains of the process industry due to approvals according to ATEX & IEC, SIL2 conformity compatibility with the established fieldbusses (HART, FF, PA) Innovative grounding concept to avoid low-frequency equalizing currents – direct and indirect shield grounding possible in one device Uninterruptible operation of the plant due to an automatic resetting
