LINETRAXX® CEP410R-2
LINETRAXX® CEP410R-2
- 預警正在形成的接地故障
- 響應範圍為 10 mA 至 30 A
- 透過 Modbus RTU 通訊
- 支援遠端狀態監測
- 緊湊、節省空間的設計
CEP410R 剩餘電流監視器用於監測中心接地點 (central earthing point)。
這款 AC 和脈動 DC 靈敏監測裝置可以連接到現有的通訊網路，達成遠端狀態監測。兩個獨立可調的響應值可用於區分預警和警報（預警設定值為所設定響應值 Idn 的 50%…100%）。
該監測裝置旨在用於監測中心接地點，以於檢測獨立 TN 系統之間的 PEN 橋和 N 導體連接。
