The 1044386 is a plug-in lightning and surge protective device designed for 3-phase power supply networks operating in isolated mode. It combines Type 1 and Type 2/Class I+II protection, making it suitable for use in low-voltage systems between L-N or L-PEN, and in IT systems between L-PE when exposed-conductive parts are present. The device features a DIN rail mounting method (top hat rail, 35 mm) and includes remote signaling capabilities. It is constructed with four poles and is compatible with various system configurations, providing reliable surge and lightning current protection for electrical installations.
