It uses a 3+1 topology, with MOV protection for L\u2013N and coordinated GDT+MOV protection for N\u2013PE, offering reliable suppression of transient overvoltages from lightning and switching surges.Its compact pluggable cartridge design allows easy replacement, while integrated thermal disconnectors ensure safe operation. Visual green\/red indicators provide status feedback, and optional RC contacts enable remote fault monitoring.<\/section>\n<section id=\"features\">\n<h3>\u0627\u0644\u0645\u064a\u0632\u0627\u062a
