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
