The importance you attach to surge protection depends on your appetite for risk. Lightning protection systems safeguard systems against fire or electrical destruction and protect people from injury. A lightning strike discharges several hundred kilovolts of electricity.
Costly repairs, downtimes and sustained revenue losses can result in the absence of lightning arresters. Reason enough to protect yourself against damage by using HAKEL lightning and surge protection devices.
With Hakel we offer an extended family of surge arresters of various types for power distribution systems, electronic equipment as well as for measurement, control and regulating signals, such as analogue and digital signal circuits, data interfaces like Ethernet Cat. 6. Protective elements are also available for your telephone system. Furthermore, we are an experienced partner at your side when it comes to lightning protection solutions and 600V, 1000V, 1200V and 1500V surge arresters for wind power and photovoltaic systems.
The products for lightning and surge protection can be used in conjunction with all Weidmüller Industrial Ethernet, power supplies, analogue signal processors as well as relays and semiconductor switches or combined to form countless complete solutions.
The range of surge protection devices is designed to safeguard remote electronic equipment from surges on signal and data cabling. Models are available in a range of working voltages to cover all process-related signals such as RTDs, THCs, 4/20mA loops, telemetry outstations, shut-down systems and fire and gas detection. The weatherproof enclosure of the Hakel range is particularly suitable for locations which are regularly exposed to lightning activity and suffer frequent damage. These self-resetting devices continue to protect even after a surge has passed making them maintenance free, again ideal for remote locations.
DTNVE 5 is a complex range of surge protection devices designed for protection of data, communication, measuring and control lines against surge effects. These surge protection devices are recommended for use in the Lightning Protection Zones Concept at the boundaries of LPZ 0A(B) - 1 according to EN 62305. All types provide effective protection of connected equipment against common mode and differential mode surge effects according to IEC 61643-21. The nominal current of individual protected lines IN< 5A.
These devices consist of MOVs only. The number of protected pairs is optional (1-2). These devices are produced for nominal voltage within the range of 12V-230V. Maximum discharge current is different according to various types from 2kA (8/20) to 10kA (8/20).
