- Applications
- Features
| Mining |
| Continuous NGR monitoring |
| Continuous NGR monitoring detects resistor failure within seconds, reduces transient overvoltage risk, removes risk of ground fault detection failure |
| Ground fault detection main or backup protection to detect a ground fault anywhere on the monitored system |
| Adjustable pickup (0.5 to 4 A)- select greatest sensitivity without false operation |
| Adjustable time delay (0.1 to 2 s)- adjustable trip delay allows system coordination |
| Selectable fail safe or non-fail safe operating modes allows connection to shunt or undervoltage breaker coil or alarm system |
| Extended resistor trip time |
