- Features
- 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 (2 to 100%) selects greatest sensitivity without false operation, adjustable in 1% increments (MEM setting)
- Adjustable trip delay allows quick protection and system coordination
- Universal CT compatibility allows the use of a CT that gives required ground fault settings
- Selectable fail safe or non-fail safe operating modes allows connection to shunt or undervoltage breaker coil or alarm circuit (trip, ground fault, resistor fault relays)
- Trip records onboard 100 event (with date and time) recorder helps with system diagnostics
- Harmonic filtering (DFT) eliminates false trips due to harmonic noise from ASDs
- Local communications mini USB port to view measured values, configure settings and check event records
- Onboard microSD card can be used for long term data logging
- Selectable latching or auto reset operation
- Unit healthy output verifies SE-330 is operating correctly
- Internal circuits are conformally coated to protect against corrosion and moisture
- Normally open K4 unit healthy contact
- Dual RJ45 ethernet communications
