1) All manual motor protectors listed are Type E self-protected up to 65 kA. See ABB publication
2CDC131085M0201 – Manual Motor Starters – North American Applications for complete technical data
on the ABB Type E manual motor protectors. In order for these manual motor protectors to be used for
branch circuit protection, they must be UL listed Type E manual motor protectors, otherwise they can be
used only as an At Motor Disconnect. "At Motor Disconnect" is a disconnect just ahead of the motor on the
load side of the panel.
2) Manual motor protectors may require adjusting the trip limit from the factory setting at or above the drive
input Amps to avoid nuisance tripping. If the manual motor protector is set to the maximum current trip
level and nuisance tripping is occurring, select the next size MMP. (MS132-10 is the highest size in the
MS132 frame size to meet Type E at 65kA; next size up is MS165-16.)
3) Requires the use of the S1-M3-25 line side feeder terminal with the manual motor protector to meet Type
E self-protection class.
4) 480Y/277V delta systems only: Short-circuit protective devices with slash voltage ratings (e.g. 480Y/277 V
AC) can be applied only in solidly grounded networks where the voltage from line-to-ground does not
exceed the lower of the two ratings (e.g. 277 V AC), and the voltage from line-to-line does not exceed the
higher of the two ratings (e.g. 480 V AC). The lower rating represents the device's interrupting capability
per pole.
5) For all drives, the enclosure must be sized to accommodate the specific thermal considerations of the
application as well as provide free space for cooling. See section
For UL only: The minimum enclosure volume is specified in the UL listing when applied with the ABB Type
E MMP shown in the table. ACS355 drives are intended to be mounted in an enclosure unless a NEMA-1
kit is added.
