Model Designation Key

This chart explains the Kohler

transfer switch model designation system. The sample

model designation shown is for a Model K automatic transfer switch that uses an
open-transition contactor with MPAC 1000

electrical controls rated at 480 volts/60 Hz,

3 poles, 4 wires, and solid neutral in a NEMA 1 enclosure with a current rating of
225 amperes. Not all possible combinations are available.
