Entellisys Low-Voltage Switchgear
Section 2. General Description
Entellisys low-voltage switchgear provides
protection, control, and monitoring in a flexible
package that will change the way you think about
switchgear. All of this capability is integrated into
industrial-duty equipment built to ANSI standards
and uses 100% rated EntelliGuard low-voltage
power circuit breakers. Entellisys low-voltage
switchgear is built upon the same design as the
rugged AKD architecture, with almost 60 years of
proven reliability. The Entellisys equipment design
is based on the AKD-10 structure. EntelliGuard
low-voltage power circuit breakers are an extension
™
of the robust WavePro
experience in all types of switchgear environments.
Entellisys low-voltage switchgear is available with
the following maximum nominal ratings:
• 600 volts ac
• 5000 amps ac
• 50/60 Hz
• 200 kA symmetrical short circuit interrupting
Entellisys switchgear is designed to have more margin
within its ratings to provide maximum continuity
of service for those applications subject to severe
duty, such as process industries, data centers,
healthcare facilities, and power systems requiring
continuous operation. It is designed to be operated
in an ambient temperature between -30°C and 40°C
and is available in indoor construction. The bus
sizing is based on temperature rise rather than on
current density (as with switchboard construction).
EntelliGuard low-voltage power circuit breakers are
available for Entellisys switchgear in six frame sizes:
800A, 1600A, 2000A, 3200A, 4000A and 5000A.
All circuit breakers can be equipped with current
limiting fuses. The 800A and 1600A frames are
provided with integrally mounted fuses, while a
separate fuse carriage is required for 2000A through
5000A type breakers.
Entellisys switchgear houses low-voltage power
circuit breakers and the Entellisys system compo-
nents in single or multiple source configurations.
Entellisys switchgear can be applied either as a
power distribution unit or as part of a unit substation.
Entellisys switchgear is manufactured in GE's ISO
9001 certified facility in Burlington, Iowa. It complies
design, with years of
with ANSI standards C37.20.1 and NEMA SG-5, and
is UL Listed to standard 1558, file no. E76012. The
switchgear has been conformance tested according
to ANSI C37.51. Entellisys switchgear also meets
the requirements for the CSA label. Entellisys
equipment has been tested and meets the IBC-
2003 requirements.
ANSI standards require that switchgear operates
at the ratings of devices installed. Switchgear
short circuit ratings are based on two 30-cycle
withstand tests with a 15-second interval between
tests, performed at 15% power factor and 635v
AC maximum.
GE's Entellisys low-voltage switchgear can help you
meet today's challenges for greater productivity,
increased operator safety, and improved equipment
reliability and maintainability.
Entellisys low-voltage switchgear offers:
• Safety – Human interface located away from
the equipment for monitoring, control, and
remote racking. Advanced zone protection
provides fast fault identification while providing
selectivity. Reduced Energy Let Through mode
lowers the potential arc flash energy when
someone is going to be near the equipment.
• Reliability – Redundant systems, selective pro-
tection, and predictive maintenance data aids in
maximizing uptime and minimizing downtime.
• Flexibility – Add or change system functionality
with no hardware changes, making it easy to keep
the equipment up to date to meet changing needs.
The Entellisys architecture enables the system to
provide these unique advantages.
