3000A Main Breaker Cubical with SSF30G330 Power Break II IntelliGuard TU Installed
3000A_Main Breaker Cubical SSF30G330 MLO, this is the latest innovation from GE. A Brand New General Electric Main Switch NEMA 1 Enclosed, Main Lugs Only (MLO) indoor, 3 Phase, 4 Wire, 480Y/277V rated, 3000 Amp. Breaker and Enclosure are still on factory pallet. EntelliGuardÂ® TU Trip Unit provide ultimate system reliability and selectivity without sacrificing circuit protection.
EntelliGuard® G circuit breakers are the newest line of GE lowvoltage circuit breakers, the next step in the evolution of a line known for exceptional reliability. The breaker’s new advanced features provide ultimate system performance without sacrificing safety or dependability. EntelliGuard® G are available in UL 489, UL 1066 (ANSI), and IEC ratings.
New capabilities in the EntelliGuard® TU Trip Unit provide ultimate system reliability and selectivity without sacrificing circuit protection.
This superior addition enhances the Power Break® II breaker with a Waveform Recognition Instantaneous Algorithm that eliminates
costly downtime due to nuisance tripping. It enables harmonic analysis four cycles prior and after an event, and discerns whether a downstream breaker/fuse is clearing the fault. The unit also includes Zone Selective Interlocking Instantaneousout (can be used as a feeder and downstream device with a power circuit breaker upstream) which delivers simultaneous and independent ZSI of Short Time, Ground Fault and Instantaneous protection, providing the ability to overlap the Instantaneous on the Main and Feeder breakers. Together, these innovative abilities achieve HRC2 with currents as high as 100kA with simultaneous flash protection and selectivity. The EntelliGuard® TU Trip Unit offers optimum circuit safety and arc flash protection with the Reduced Energy Let-Through function, providing a faster instantaneous trip that may be used if faster and more sensitive protection is required temporarily. It is commonly referred to as an “Arc Flash Switch” or “Maintenance Switch”. The new and improved trip unit design delivers selectivity tools not previously available in GE circuit breakers:
