  • 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
