Arc Flash and Selectivity at the same time
The EntelliGuard? TU Trip Unit offers optimum circuit
protection
and optimum system reliability simultaneously with
little or no
compromise to either of these critical functions.
Reliability and arc
flash protection, in one package, at the same time,
all the time.
Algorithms enabling arc flash protection and
selectivity
—RELT – Reduced Energy Let Through
—Zone Selective Interlocking – Instantaneous (ZSI-I)
—Waveform Recognition Instantaneous – Coordinate
with Current
Limiting Devices and reduces Nuisance Trips
—Flexible Time Current Curves – Create the shape you
need
Reliability – Health Status
—Non-volatile memory with continuous self-testing
microprocessor
—Health Status LED indicates Normal Operation,
Errors, Pick-up, Trip
—External Power Not Required with Long Life Lithium
Battery
—Positive setpoint recognition, values flash until
saved
Plug and Play
—Same Form, Fit, Function as the popular
MicroVersaTrip? Trip
Unit. Easily upgrade an existing converted breaker1
Optional Full-function metering including
—current (Amps, kAmps)
—voltage (Ph-Ph, Ph-N)
—energy (kWh, MWh, GWh)
—real power (kW, MW)
—total power (kVA, MVA)
—frequency (Hz)
—demand (avg. kW, MW) and peak demand
Optional protective relaying functions include
—undervoltage
—overvoltage
—voltage unbalance
—current unbalance
—power reversal
—power direction setup
1Note: Some options require 24VDC, additional hardware
to enable Metering,
Relaying, RELT, ZSI, Modbus to be added to the
Breaker, Equipment Cubicle,
and Equipment Sections.

For converting AK-2 version breakers and newer, not
applicable for AK-1 or AKR
Breakers equipped with older style open fuse lockout
devices (OFLO), must be
retrofitted with newer style OFLO device prior to
conversion process.
Order replacement OFLO kits as follows: AKU-50 - order
OFLO kit #121C287OG2,
AK-75 - order OFLO kit #121C287OG3, AK-100 - order
OFLO kit #121C287OG4
