Combined Lightning and Surge Arrester Mov and Spark-Gap
อุปกรณ์ป้องกันเสิร์จในระบบไฟฟ้าสำหรับติดตั้งภายในตู้ MDB ช่วยป้องกันความเสียหายของระบบไฟฟ้า
จากเสิร์จในย่าน อีกทั้งยังช่วยป้องกันผลกระทบอันเนื่องจากสภาวะ Overvoltage และ Switching Overvoltage ที่เกิดขึ้นในขณะฟ้าผ่า
pluggable module, visual fault signalling, module locking
- three-pole varistor lightning current arrester
- installation at the boundary of zones LPZ 0 and LPZ 1 or higher, for objects in LPL III and IV
- for protection against impact of partial lightning currents, induced overvoltages during a lightning strike or switching overvoltages
