It takes about 20 minutes to install a feature-for-feature LSI assembly. This includes racking

9 - Product Specs
GE AKD-5 Low Voltage Switchgear (LVS) is a free-standing assembly of metal-enclosed ANSI
power circuit breakers. It may also be a part of a single-ended or double-ended load center
unit substation. AK25/AK50 Retrofill are based on Cradle in Cradle (CiC) solution whereas
Views
Typical Emax 2 Retrofill circuit breakers for GE AKD-5 & OEM switchgear are shown below.
All circuit breakers are drawout types. Each Retrofill is constructed by permanently joining
an Emax 2 circuit breaker in a steel frame, installing primary and secondary disconnects
and driving drawout racking cams thru what look the Emax 2 Cassette’s front dashboard.
With least modifications to be made to existing switchgear, Emax 2 Retrofill breakers are
cost effective solution to upgrade the existing electrical system. Direct Replacement is the
solution where the moving part of circuit breaker is removed and a new circuit breaker is
provided, which racks into the existing switchgear compartment. The direct replacement
retrofitting kit allows a reliable upgrade of the old GE legacy breakers to new Emax 2
Retrofill Breakers Range.
Below figures (front and back views with finger clusters) present Emax 2 Retrofill breakers,
which can replace AKR breakers.
