￭ Manual self-protected combination motor controller – Type E USA
(UL (NEC))
You can use the ABB Type E manual motor protectors (MMP) MS132 & S1-M3-25, MS165-xx
and MS5100-100 as an alternate to the recommended fuses as a means of branch circuit
protection. This is in accordance with the National Electrical Code (NEC). When the correct
ABB Type E manual motor protector is selected from the table and used for branch circuit
protection, the drive is suitable for use in a circuit capable of delivering no more than 65 kA
RMS symmetrical amperes at the maximum rated voltage of the drive. See the table below
for the appropriate MMP types and minimum enclosure volume of IP20 / UL open type drive
mounted in an enclosure.
Note: The UL Listing of drive and MMP combinations applies only to drives that are mounted
in appropriately sized metal enclosures that are capable of containing any drive component
failure. Wall-mounted drives with UL type 1 kits (optional) are not covered by the UL
combination listing of drives with MMPs.
WARNING! Use fuses for the short-circuit protection of a wall-mounted drive with
the UL type 1 kit (optional). Serious injury, fire, or damage to equipment can result
from the use of MMPs instead of fuses.

1) All manual motor protectors listed are Type E self-protected up to 65 kA. See the 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) 480Y/277 V 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.
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
