Surge Arrester HAW562
Technical Data
CompareSurge arrester
| Measuring Principle | Surge arrester |
| Measuring principle | Surge arrester for DIN rail mounting |
| Function | Surge arresters are applied to protect electronic components of a plant against overvoltage! Due to this investment intensive measuring instruments are protected and the plant availability is increased. |
| Application | Surge protection for power supply or signal / communication cables |
| SIL | 2 |
| Certificates | ATEX IECEx Ex ia[ia Ga] + CSA C/US IS |
The HAW562 protects electronic components against overvoltage. It ensures safe earthing of overvoltage surges in signal lines (e.g. 4...20 mA), communication lines (fieldbus) and supply lines. The function of the protected transmitter or electronic components is not affected.
Advantages
Protects expensive measuring equipment
Increases plant reliability because the surge arrester is precisely matched to the electronic components in process automation and process measurement technology
Use in hazardous areas - optional SIL2 intrinsically safe approval
Vibration and shock tested in accordance with EN 60068-2
Direct and indirect shield earthing
Application areas
The surge arrester attenuates residual currents from upstream lightning protection steps and limits system-induced or generated overvoltage surges.
The HAW562 unit is mainly used in process automation as well as in measurement and communication technology in the chemical, pharmaceutical, water and wastewater, and food industries.
