>Область применения

The HAW568 surge protective device is used to protect electronic components in field devices from being destroyed. It ensures that overvoltage surges which occur in signal cables (e.g. 4 to 20 mA), in communication lines of Field buses and in power lines are safely limited or passed into the ground. The functionality of the electronic component to be protected is not affected as, using the impedance-free connection of the protection unit, interference voltage drops cannot be introduced.

Surge protective devices are used to weaken residual currents from upstream lightning protection steps and to limit system-induced or system-generated overvoltage surges
HAW568 units are primarily used in process automation and measuring and communication technology within the water & wastewater, chemical, oil & gas as well as power & energy industry
Compact device for the protection of signal/communication cables or for the simultaneous protection of signal, communication and power supply cables
