It is connected to the power line of three-phase power supply and distribution system in parallel to prevent damage to power supply system and electrical equipment caused by impulse surge and transient overvoltage caused by lightning stroke. This product has the advantages of large reserve. The test waveform of the primary lightning arrester in the T1 test is 10/350us, which simulates the waveform of direct lightning strike, so if the outdoor distribution box is an overhead line When the risk of direct lightning surge intrusion is introduced, a first-level lightning arrester should be. OBO Bettermann is one of the world's most experi-enced manufacturers of lightning and surge protection systems. For almost 100 years, OBO has been devel-oping and producing standard-compliant lightning pro-tection components. Equip your electrical systems with our surge. The lightning power/circuit tvss breaker box is a kind of lightning surge protection device (SPD), which is mainly installed in the power distribution room, power distribution cabinet, AC power distribution panel, switch box, fuse box, meter box, outdoor electrical box and other important equipment. Lightning strikes pose a significant threat to outdoor electrical infrastructure, particularly ACDB panels (AC Distribution Boxes) used in renewable energy and telecom applications.
