22 ACS880-01/04 +C132 marine type-approved drives
Ambient temperature derating
ACS880-04 drive modules, ACS880-01 IP21 (UL Type 1) drive types and other
IP55 (UL Type 12) types than listed in the following subheadings
In the temperature range +40…55 °C (+104…131 °F), the rated output current is
derated by 1% for every added 1 °C (1.8 °F).
To calculate the output current, multiply the current in the ratings table by the derating
factor (k):

Continuous rms output current allowing 50% overload for 1 minute every 5 minutes.
* Continuous rms output current allowing 40% overload for 1 minute every 5 minutes.
** Continuous rms output current allowing 44% overload for 1 minute every 5
minutes.
*** Continuous rms output current allowing 45% overload for 1 minute every 5
minutes.

Typical motor power in heavy-duty use
Note 1: The ratings apply at an ambient temperature of 45 °C (113 °F).
Note 2: To achieve the rated motor power given in the table, the rated current of the drive must be higher
than or equal to the rated motor current.
ABB recommends DriveSize dimensioning tool for selecting the drive, motor and gear combination.
