Trip Unit

All the electrical industry buzzwords—system coordination, selectivity, reliability, arc flash protection—are addressed with GE’s trip unit.

09/14/2010


Now offered in GE Spectra SG600 and SK1200 circuit breakers, and backwards compatible with existing Spectra MicroVersa Trip breakers, GE’s microEntelliGuard trip unit delivers: 

  • Flexible time-current curve shaping in the industry for system coordination
  • Instantaneous ZSI (Zone Selective Interlocking) for selectivity
  • Waveform capture and event log for reliability
  • Reduced energy let-through (RELT) for arc flash protection.

The trip unit also features:

  • An HMI (human machine interface) based on the same platform as the trip units that provides a backlit LCD display with five-button tactile keypad and LED status to show the “health” of trip unit
  • Fully adjustable time-current curves with multiple curve shapes, slopes, and delay bands
  • Ground Fault Trip or Alarm with multiple slopes for system coordination
  • Current metering is a standard feature, with options for power, energy and reactive power metering and waveform capture
  • Event Log with date/time stamp to record the last 10 events
  • Test set jack for GTUTK20 test kit
  • Modbus communications system with user-selectable address assignment for communication directly with building-power management systems.

Specification engineers are available to assist end-users and consulting engineers with system design to fully optimize the capabilities of the microEntelliGuard trip unit.
