EntelliGuard G Power Circuit Breaker

Section 6. Application Data

Introduction

The EntelliGuard G family of circuit breakers and related
switching devices is a truly global line of protection and
switching devices. It was designed from the ground up to
provide reliable protection and operation in a wide range of
power distribution systems. Combined with the EntelliGuard
TU family of trip devices, EntelliGuard G circuit breakers
provide superior protection and reliability with a maximum
of flexibility and a minimum of compromise for your power
protection and switching needs.
This section provides an overview of the circuit breaker's
capability under UL 489 and UL 1066 standards.

Key Features

There are three product families:

All Types

•
Stationary mounting capability with rear or front
connections.
•
Draw-out mounting with cassette and automatic shutter
mechanism.
•
Complete closed door operation capability – UL489,
ANSI or IEC.
•
Two-step stored energy mechanism for manual or
electrically operated circuit breakers, suitable for fast
throw-over or generator paralleling applications
•
Remote racking device allowing maintenance personnel
to rack circuit breakers in and out while standing outside
the arc flash boundary.
•
3 and 4 pole configurations with the neutral on either
side.
•
Suitable for UL1008 transfer switch applications
•
Alternate, settable and remote controllable
instantaneous pickup with positive feedback.
•
Industry's only fully controllable ZSI restrained and
unrestrained settings.
•
Industry's only fully selective instantaneous trip with
selectivity enhancing ZSI capability.
•
Field installable accessories with labels that may be
seen through the circuit breaker's escutcheon.
•
Easily accessible terminal contacts at the top or side of
circuit breaker for use by installer – permanently labeled,
color coded and interlocked with harnesses for fast,
efficient, mistake-proof wiring.
•
Advanced protection algorithms that allow maximum
selectivity and protection at the same time with
minimized need to sacrifice protection to get system
reliability or visa versa.
•
Trip curves and algorithms to optimally accommodate
downstream fuses, older slower power circuit
breakers, ultra fast current limiting devices or other
EntelliGuard circuit breakers without sacrificing any
more protection than absolutely necessary to achieve
significant selectivity.

Ratings and Sizes

The EntelliGuard G family of overcurrent devices is available
in 3 or 4 pole versions, in 3 physical sizes referred to as
"envelopes" 1, 2 and 3. Four pole versions may have the
neutral on the right- or left-most pole. The envelope and the
number of poles are the main determinants for physical size
and the space the device will require when installed in
equipment or enclosures.
The circuit breakers and switches are further divided into
"frame" sizes. The frame sizes follow the guidelines defined
