- product introduction:Features
◆ Loss of zero line protection;
◆ Indication of loss of ground wire;
◆ Clear fault display;
◆ Stable and reliable functions;
◆ When used in a three-phase four-wire circuit, the zero line and the ground wire can be shorted;
◆ Accuracy of voltage setting: 0.5% (Set value×0.5%); Temperature drift: 0.05V/℃ (Benchmark temperature: 25℃).
Functions
◆ Protection functions: overvoltage, undervoltage, phase sequence, dynamic phase loss, static phase loss, voltage unbalance, loss of zero line, electrification of zero line, supervoltage of zero line;
◆ Indication of normal conduction of ground wire;
◆ Time delay functions: delay output, delay recovery, power-on delay.
