Earth Leakage Protection Relay DIN 300/300E – Mikro

Earth Leakage Protection Relay เป็นอุปกรณ์ป้องกันอิเล็กทรอนิกส์ที่ใช้ไมโครโปรเซสเซอร์ที่ออกแบบมาเพื่อตรวจจับการรั่วไหลของกระแสไฟในระดับต่ำ

Products Feature : DIN 300 / 300E

  • Selectable earth leakage sensitivity between 30mA – 30A.
  • Selectable time delay between 0 msec – 3 sec
  • Earth leakage level indicator on panel
  • Detection of no connection with ZCT
  • Output relay trip indicator
  • Trip starting indicator
  • Protected against nuisance tripping
