- ▪ The ground fault (leakage) status of the electric line is alarmed and displayed for each circuit, and the ground fault current in the event of a ground fault is displayed on the LCD display
- ▪ It stores the ground fault current value at the time of an accident and can be used as data for condition analysis after a fault
- ▪ Built-in communication port enables remote monitoring (optional function)
- ▪ Provides convenient HMI through key interface
- ▪ Malfunction can be prevented against harmonic components and various noises
Voltage class
- ▪ Deesys specifies this relay for protecting ground faults on circuits below 600 V
- ▪ Pair with the low-voltage Deesys ZCTs: DZR (round cable-through), DZS (square busbar-through) or SZR
- ▪ Not the relay for the high-voltage HZR ZCT (6,600 / 3,300 V), whose catalog specifies HGR / DGR relays
