Working through combination of communication algorithms across GE portfolio of circuit breakers, ArcWatch uses instantaneous zone selective interlocking and waveform recognition to ensure only circuit breakers nearest to fault trip, which happens in as little as 4 ms. Systems embedded with ArcWatch technology minimize impact of arc-flash event to less than 8 cal/cm². ArcWatch-enabled circuit breaker families include EntelliGuard, Record Plus, and Spectra RMS series.
