8.5.2 Replacing the motor circuit-breaker
The PKE32/XTU-32 motor protection switch, item no. 03098183-01, can be used in 3 x 208 VAC
± 5% and 3 x 230 VAC ± 5% supply voltages. The position of the motor protection switch is shown
in Fig. 8 - 2
on page 260, item MS1. 8
– Remove the old complete MS1 & MS1A and replace them with the new MS1 (PKE32/XTU-32).
– This MS1 PKE32/XTU-32 part is backward compatible to the old MS1/MS1A.
– Insert the new MS1 (PKE32/XTU-32) at the same location as the old MS1 position.
– Set the over current and short circuit trip threshold settings as shown below.
