Low Voltage Power & Insulated Case Circuit Breakers Section 8 WavePro Circuit Breakers with EntelliGuard ™ TU, Power+, Enhanced MicroVersaTrip ™ Plus and MicroVersaTrip ™ PM Trip Unit Systems

Instantaneous Protection —Instantaneous pick up is adjustable up to 15 times plug rating on every circuit breaker and, optionally, up to 30 times on some breakers. —A separately adjustable fast instantaneous trip — useful for when the circuit must provide the best possible protection and arc flash performance while sustaining normal load —An override instantaneous provides fast tripping for the largest bolted fault currents to minimize potential damage. —Up to 17 Short Time bands allow you to set your circuit breaker to sustain load requirements without slowing protection. —Ground Fault Alarm via I/O, or —Ground fault protection with faster time bands, multiple slopes and the ability to coordinate a 1200A ground fault with an 800A circuit breaker — a ratio four times better than in previous generation trip units Maintenance and Diagnostics —Universal spare trip unit that will fit any GE circuit breaker —Universal trip plug fits any trip unit —Flexible serial communication via Modbus RTU —Integrates directly into GE’s EnerVista ™ Power Management System —Health status via breaker LED indicating normal operation, errors, pickup, and trips while providing non-volatile memory with a continuous self-testing microprocessor —Lithium battery to eliminate need for external power —10 event Log with Date/Time Stamp: Stores the last 10 events. Date/Time with 24VDC Power. —Thermal Memory —WaveForm Capture: 40 Samples/Cycle, 4 cycles prior and 4 cycles post event in COMTrade format —Large backlit LCD with detailed, easy to see descriptions

There are four trip unit systems available for WavePro Low Voltage Power Circuit Breakers — EntelliGuard ™ TU, Power+, Enhanced MicroVersaTrip ™ Plus and MicroVersaTrip ™ PM. All four systems consist of the trip unit, the trip actuator, current sensors and rating plugs. The term “trip unit systems” applies to the combination of these four components, which form the circuit breaker solid-state tripping system. The EntelliGuard ™ TU Trip Unit is the latest addition to the list of trip units available on GE low voltage power circuit breakers. The new functions offered by the trip unit enhance the WavePro breaker with Waveform Recognition Instantaneous which improves coordination with current limiting devices and reduces nuisance trips by discerning whether a downstream breaker/fuse is clearing the fault. The unit also provides optimum circuit safety and arc flash protection with the Reduced Energy Let Through, providing a faster instantaneous trip that may be used in case faster and more sensitive protection is temporarily required. Its Zone Selective Interlocking provides the ability to overlap the Instantaneous on the Main and Feeder breakers and the EntelliGuard ™ TU also has Flexible Time Current Curves: 44 Long Time Shapes (I 2 T and I 4 T (fuse)), 3 Short Time I 2 T slopes, Short Time adjustable in 55 msec increments and a Selective Ground Fault curve. All of the new functions and features in the new EntelliGuard ™ TU trip unit provide ultimate system reliability and selectivity without sacrificing circuit protection. Designed for Flexibility —A wide range of continuous adjustment Long Time delays ensure the circuit breaker can be exactly dialed in to your selectivity and protection needs. —Multiple Short Time diagonal bands tune your protection to exactly where it needs to be. —Flexible time current settings and curves — Standard Long Time characteristics exactly mimic the curve of a thermal magnetic circuit breaker. —Flexible Time Current Curves: 44 Long Time Shapes (I 2 T and I 4 T (fuse)), 3 Short Time I 2 T slopes, Short Time adjustable in 55 msec increments, a Selective Ground Fault curve
