EntelliGuard G - Previous Generation Circuit Breakers are low-voltage power circuit breakers manufactured by ABB at the Florence, SC (USA) facility. The EntelliGuard G, E, and R series are available in 3- and 4-pole designs, rated from 400A to 6000A, with fault interruption ratings up to 200 kAIC. As part of ABB Electrification Service’s global lifecycle management, the EntelliGuard G is in a limited phase but not obsolete, with all required spare parts and replacement circuit breakers fully available. The EntelliGuard TU Trip Unit system provides superior arc flash protection and selectivity, supporting Modbus RTU or Profibus DP communication protocols. These breakers are used in AKD-20 and Entellisys low-voltage switchgear and switchboards.
