Description
- USB port simplifies local connections and speeds up relay communications.
- Default displays or programmable custom messages notify personnel of power system events or relay status.
- Front-panel LEDs alert operators in the substation to faulted phases, the relay’s status, and element operation.
- Optional SafeLock® trip/close pushbuttons and bright indicating LEDs allow breaker control independent of the relay.
- High-current interrupting output contacts increase contact robustness and reliability.
- Harmonic metering to the 16th harmonic enhances power quality analysis.
- SafeLock® trip/close pushbuttons on the front panel are wired directly to these terminals to allow breaker control independent of the relay.*
- Expanded I/O allows for flexible applications.*
- Sensitive earth fault (SEF) protection accurately detects ground faults with low current values.*
