Life Extension: GE's New EntelliGuardÂ® TU Trip Unit Conversion/Upgrade Kits Deliver 'Plug and Play' Solution to Help Decrease Arc Flash Hazards, Increase Electrical System Reliability

Plainville, CT - GE has channeled decades of circuit breaker trip unit experience to develop its new EntelliGuardÂ® TU Trip Unit Conversion/Upgrade Kits, ideal for electrical service organizations, contractors and industrial end users concerned with improving arc flash protection without sacrificing system reliability, while maintaining and extending the life of an electrical power system.

The EntelliGuard Â® TU Trip Unit includes both a Waveform Recognition Instantaneous Algorithm and Zone Selective Interlocking Instantaneous, which together can achieve HRC2 or better without sacrificing selectivity for available fault currents as high as 100kA. Other options include a feature called Reduced Energy Let Through (RELT) that provides enhanced arc flash protection during maintenance.

"Normal wear and tear of aging trip devices on low voltage circuit breakers can lead to loss of calibration that jeopardizes system coordination, protection and reliability," says Darrin Bock, Product Manager. "Our 'plug and play' EntelliGuardÂ® TU Trip Unit Conversion/Upgrade Kits help extend the life of mechanically sound breakers, eliminate nuisance tripping, and improve electrical system coordination and protection."

Available to install on legacy GE breakers such as AK, AKR, Power Break(TM) and WavePro(TM) series low voltage circuit breakers, the new kits extend the offering to non-GE manufactured breakers including Allis Chalmers, I-T-E, and Westinghouse, while providing all the hardware needed for options like RELT in one easy to install kit.

While delivering an easy solution to reduce arc flash hazards without having to sacrifice system reliability, GE's EntelliGuardÂ® TU Trip Unit Conversion/Upgrade Kits offer:

Flexible time current settings and curves (Including Fuse Shapes);

Zone Selective Interlock - GF, S, and I

RELT - Reduced Energy Let Through

Ground Fault Alarm via I/O or Modbus Communications

Easy upgrades to Power Management Control Systems (PMCS) via open Modbus RTU protocol;

Large LCD screen to centrally display three phases on one screen

10 Event log with date and time stamp;

Health status via breaker LED indicating normal operation, errors, pickup, and trips while providing non-volatile memory with a continuous self-testing microprocessor;

Free set-up software that let facilitators easily program all units offline and analyze captured waveforms;

Full-function metering and relaying; including Waveform capture to enable harmonic analysis 4 cycles prior and after event;

Thermal Memory;

Lithium battery to eliminate need for external power.
