1) All manual motor protectors listed are Type E self-protected up to 65 kA, except MS165-80 which is
Type E self-protected up to 50 kA. See the ABB manual motor starter catalog (1SBC100214C0201) 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) 480Y/277 V Wye 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).
3) 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 65 kA; the next size up is MS165-16.)
4) 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. Refer to the technical data. 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.
5) Requires the use of the S1-M3-25 line side feeder terminal with the manual motor protector to meet
Type E self-protection class.
6) Enclosures for R3, 240V and R3, 480V drives must have a solid bottom directly below the drive i.e. fans
(other than internal stirring fans), filters or louvers cannot be mounted directly below the drive but
can be mounted in adjacent areas on the bottom of the enclosure.
