HAW566 surge arrester, DIN rail surge arrester installed in control cabinets to protect power supply and communication cables
Advantages
-
Protects electronic components and increases the availability of process automation plants in the field
-
Installed directly in field devices, easy to operate and space-saving
-
Optional SIL3
-
Side-by-side installation reduces loop resistance (screw-terminal version)
-
Plug-in device without additional cable entries
Field of application
The HAW568 surge arrester protects the electronic components inside field devices from damage. It limits overvoltage surges occurring on signal cables (e.g. 4...20 mA), fieldbus cables and power supply cables, or safely diverts the surges to ground. The zero-impedance connection of the protective device avoids interfering voltage drops and ensures that the electronic components function properly.
-
The surge arrester reduces residual currents occurring on upstream lightning protection devices and limits systematic overvoltage surges
-
The HAW568 surge arrester is mainly used on process automation instruments in the water and wastewater, chemical, oil and gas, and power and energy industries
-
Compact design protects signal, communication and power supply cables
