Alternate short-circuit protection
You can use the ABB Type E manual motor protectors 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 drive’s maximum
rated voltage. See the following table for the appropriate ratings. See the MMP rating
table for the minimum enclosure volume of IP20 open type ACS355 mounted in an
enclosure.
Drives with and without NEMA 1 enclosure kits are included in the UL file. The MMP
selections in the table are also valid for drives having a NEMA 1 enclosure kit
installed.
