vertical bus. Model 2 was introduced in 1983 to accommodate revised wire harness routing. Model 3 was
introduced in 1991, using a flat bar vertical bus. AKR breakers use MicroVersaTrip 9, MVT RMS9, EPIC, MVT Plus,
MVT PM, or EntelliGuard TU trip units. Aluminum bus was removed from the design in 1996 in favor of the standard
tin-plated copper bus (silver plated optional).
The AKR-30/50/50H/T50 breakers used in AKD8 have 5” deep plastic front escutcheon& spring loaded sliding
“picture frame”. They are drawout letter code “D” i.e. AKR-7D-30. In AKD-8, most 800-2000A breakers are “feeder”
breakers with vertical lower stud & primary disconnect fingers clusters, but 800-2000A breakers designated as
“Main” breakers, have horizontal lower finger clusters, which is the same as “D” letter code breakers sold to OEM’s.
A lower stud rejection bracket differentiates between lower stud orientations. EntelliGuard R breakers with a
catalog number beginning with
R3

EntelliGuard R breakers with a catalog number beginning with
R6

AKD-10—WPS-08, WPH-08, WPX-08, WPS-16, WPH-16, WPS-20
AKD-10 was manufactured in Burlington, IA from 1999 thru 2015. The switchgear compartment sizes and main &
vertical bus arrangements are the same as AKD-8 Model 3. The compartments have pull-out rails. AKD-10 uses
WavePro * drawout-only style breakers. All breakers have 4 rollers which align with the compartment rails. The
secondary control wiring for all functions is connected thru either one or two 36 point secondary disconnects with
gold plated contacts. Secondary control wiring terminates at fixed standard locations on the 36 point disconnects.
Each breaker has a pump style manual charging handle and manual push OPEN and Push CLOSE buttons. The
front escutcheon is 5” deep with a sliding picture frame, but is wide enough so the trip unit and new style bell
alarm are visible thru the front door of the switchgear. EntelliGuard R breakers with a catalog number beginning
with
R7
will replace a WavePro breaker with a catalog number beginning with WE or W1. EntelliGuard R breaker
with a catalog number beginning with
R8
will replace a WavePro breaker with a catalog number beginning with
WS or W2. Note Switchboard plants initially shipped “WS” style breakers and later shifted to “WE” style breakers
to be consistent with Switchgear from Burlington, Iowa.
