The economic and safety implications of lightning can be devastating. In general, the highest point of a facility is the most vulnerable to a direct lightning strike. Lightning rods or air terminals are needed to capture the strike to a preferred point and to safely conduct the energy to ground to minimize the risk. The nVent ERICO Dynasphere air terminal provides a preferred point for lightning discharges which would otherwise strike and damage an unprotected structure and/or its contents. The primary function of an air terminal, or air termination system, is to capture the lightning strike to a preferred point, so that the discharge current can be directed via the downconductor(s) to the grounding system. - Dynamic response to the approach of a lightning downleader - Non-radioactive technology - No external power required - Three replaceable terminals for specific elevation requirements Material - Stainless Steel 316 (EN 1.4401) Temperature - -40 to 100 °C Effective Projected Area - 270.96 mm² Diameter (Ø) - 25.7 mm Height (H) - 22 mm Thread Size - 1/2 BSPP Unit Weight - 2.6 kg Certifications - Qualifoudre| UL Standard Packaging Quantity - 1 pc UPC - 78285664528 EAN-13 - 8711893024753
