2005- Entellisys Introduced October 2005 as a new

platform for low voltage switchgear. Uses non-

automatic EntelliGuard
present breakers (similar to WavePro except no current

sensors, no trip unit, and limited accessories).

Entellisys uses redundant
components for highest reliability and maximum up-

time. Redundant CPU’s perform all protection,

metering, control,
and monitoring functions. Other redundant components

of the system include 2 UPS’s, 2 network

communication
switches for internal communication, 2 control power

throwover relays, 2 control power sources (120vAC).

Each breaker
cubicle is provided with an EntelliGuard Messenger,

which is the interface between the CPU’s and the

circuit breaker
operating mechanisms. The Messenger performs A/D and

D/A conversions plus provides back-up overcurrent

proteciton
for the breaker if all control power and

communications are lost.
Equipment construction is the same as AKD-10

switchgear (frame, bussing, drawout cubicles, etc).

Entellisys does
not replace AKD-10. Both product lines are currently

being produced.

AK-25 Breaker with EntelliGuard? TU Trip Unit
Low Voltage Power and DC Circuit Breakers
Trip Unit Conversion Kits
EntelliGuard? TU Conversion Kits
GE offers a complete line of trip unit upgrade kits

for low voltage
power circuit breakers manufactured by GE, as well as

by
Westinghouse, I-T-E, and Allis-Chalmers. These

conversion kits
contain everything necessary to convert an old-style

electromechanical
or solid-state trip unit to today's latest electronic,
