EntelliGuard G Power Circuit Breaker
Section 1. Introduction
®
EntelliGuard G circuit breakers are the newest line of low voltage power circuit
breakers (LVPCBs) evolved from the exceptional designs and practices of GE legacy
breakers. EntelliGuard G breakers offer a truly global product platform that meets
industry standards throughout the Americas, Europe and Asia (ANSI, UL, CSA, IEC,
Lloyds Register of Shipping, etc.).
Breakers are available in 3 and 4 pole designs from 400A to 6400A (IEC) with fault
interruption ratings up to 150kAmps. New, state-of-the-art EntelliGuard Trip Units
enable the breakers with advanced technology that provides system protection, local
and remote monitoring, relaying and communications. EntelliGuard Trip Units may be
supplied with either Modbus or Profibus communications protocols. The breaker-
trip unit system delivers superior circuit protection without compromising selectivity
or arc flash protection. The EntelliGuard system is yet another evolution of GE's core
competencies in reliable electric power distribution, circuit protection and safety.
EntelliGuard G breakers are the standard in GE AKD-20 Low Voltage Switchgear.
The breakers are suitable for 480vac and 600vac applications, and they provide
advanced circuit protection, limit arc fault energy and preserve system coordination
without sacrificing any of these critical functions.

EntelliGuard G devices are available in all standard, 100% rated, ANSI, UL and IEC
ratings in both fixed and draw-out designs. Standard devices are also offered in 4
pole designs. No compromise (e.g., derating) is necessary in the system protection
scheme as the EntelliGuard G Neutral poles are fully rated. Front and rear access
connections are available, and all configurations can be manually or electrically
operated with multiple and redundant accessories (optional).
