The FLASHTRAB-MB surge protective device from Phoenix Contact is based on innovative carbon spark gap technology and meets high lightning protection requirements.
The new FLT-MB-T1-264/12.5…UT-R surge protective devices are available in three different circuit versions. They are therefore suitable for use in 1-phase TN-S or TT systems as well as in 3-phase TN-C, TN-S, or TT systems. The surge protective devices are designed to protect residential and functional buildings. However, they can also be used universally in industrial plants and in applications with exposed locations and high lightning density. Due to the innovative triggered carbon spark gap technology, lightning currents are handled safely and surge voltages are limited. The surge protective devices meet high lightning protection requirements and are developed, tested, and approved in accordance with EN 61643-1 (DIN EN 61643-11). The devices can therefore be used in all power supply systems with a nominal voltage of 230/400 V AC.
