EntelliGuard R Circuit Breaker Retrofill AKD-8 Installation Manual DEH41549 R05

AKD-8—Neutral Disconnect Assembly, Bus Compartment

The AKD-8 EntelliGuard R Circuit Breaker uses an air-core Rogowski Current sensor to measure current level.
Legacy AK and AKR breakers used iron core CTs. For the Retrofill breaker to calculate the current levels on a
4-wire circuit, the Neutral Iron Core CT in the cable compartment needs to be replaced with a Rogowski style
CT.

The Rogowski CT comes mounted on copper bars matching the same hole-pattern as the existing neutral
bar. Neutral CT wires from the Rogowski coil to the AKD-8 gray terminal blocks must be run as a “twisted
pair”.

Table 8

shows the Rogowski assembly part numbers for AKD-8 Switchgear.

AKD-8-Neutral CT Adapter 400A-5000A

This is a miniature Rogowski coil. It mounts between the incoming Neutral disconnect and the breaker trip
unit. It converts the signal from an iron Core Neutral sensor to a Rogowski voltage output which is wired to
the Breaker's Trip Unit Neutral input connections.

The Neutral CT Adapter supports iron core Neutral sensors compatible with MicroVersa Trip, MVT RMS-9,
MVT Plus & PM, Power Plus, Pro Trip and EntelliGuard TU rated from 150 to 5000 Amps as used in GE
switchboards and switchgear from 1979-2015.  It is available in five variations (shown in Table below).
