المميزات والفوائد
- Type 1+2 combined classification handles both direct lightning impulse current (Iimp 25 kA, 10/350 µs) and switching transients (In 20 kA, 8/20 µs) in a single DIN-rail device, eliminating the need for two separate SPD stages in main distribution boards.
- Replaceable varistor cartridge design separates the wearing element from the permanent mounting base, allowing field replacement of the varistor without re-wiring — reducing maintenance cost and distribution board downtime when SPD elements degrade.
- Remote fault signalling via floating change-over contact integrates SPD health status into building management systems, generator control panels, and SCADA systems, enabling proactive maintenance scheduling before SPD failure leaves equipment unprotected.
- Voltage protection level Up ≤1.0 kV limits residual transient overvoltage to within the IEC 61000-4-5 Level 4 (2 kV) impulse withstand capability of industrial control equipment, protecting PLCs, drives, and instrumentation downstream.
- Available in TN-S, TN-C-S, and TT earthing configurations covers the three predominant LV distribution earthing arrangements used in Saudi Arabia's industrial and building installations, ensuring correct installation in all project types.
- IEC 62305-4 lightning protection zone (LPZ) boundary compliance enables the 5TC8 to serve as the Zone 0B-to-Zone 1 transition SPD when installed at the main distribution board, providing the coordinated surge protection architecture required by SASO earthing standards.
- DIN rail 35 mm mounting and compact 2-module-wide footprint allows the 5TC8 to be installed in any standard DIN rail distribution board without modification to the board layout, even in retrofit projects with limited space.
التطبيقات الصناعية
- Main distribution board SPD protection for industrial facilities in Saudi Arabia's Asir highlands and northern regions where lightning density exceeds 4 flashes/km²/year, where Type 1+2 combined protection at the LV incomer is mandatory under IEC 62305-4.
- PLC and VFD cabinet SPD for petrochemical plants in Jubail and Yanbu, where switching transients from large motor start-stop operations on shared MV buses propagate to sensitive SIMATIC S7 control system power supplies.
- Generator output board protection at emergency generator systems in Saudi hospitals, data centres, and telecommunications facilities, where the high transient voltages from diesel generator load-switching events require Type 1 arrester capability.
- HVAC building services distribution board protection in commercial towers across Riyadh and Jeddah, where IEC 62305-4 lightning risk assessment for tall buildings mandates coordinated SPD at each lightning protection zone boundary.
- Outdoor electrical installation protection at SEC substation LV auxiliary power supply boards in coastal areas near Dammam, Al Khobar, and Yanbu, where salt-air humidity increases the probability of secondary arc flashover following lightning-induced transients.
- Water utility pump station distribution board SPD for NWC remote pumping facilities in rural Saudi Arabia, where exposed overhead supply lines are susceptible to direct and induced lightning strokes during seasonal storms.
- Telecommunications tower base station power protection at STC and Zain tower sites across the Kingdom, where lightning exposure of tall steel structures demands coordinated Type 1 protection at every distribution board feeding active equipment.
