AKD-8—AKR30H, AKR30L, AKR50H, AKR30S
The AKD-8 was produced from 1981 to 1999. Models 1 and 2 have extruded vertical buses. Model 2 was
introduced in 1983 to accommodate automated wiring programs and harness routing. Model 3 was
introduced in 1991, using a flat bar, vertical bus. AKR breakers use MicroVersaTrip 9, RMS9, EPIC, MVT Plus,
MVT PM trip-units. The aluminum bus was removed from design in 1996 in favor of the standard
tin-plated, copper bus (silver plating optional). Field convertible space compartment design was added to
allow empty compartments to be modified for functioning breaker compartments without modifying the
vertical bus.
