Common DC connection
Efficiency
Degrees of protection
The brake resistor output is conditionally short-circuit proof by
IEC/EN 61800-5-1 and UL 508C. For correct fuse selection, contact
your local ABB representative. Rated conditional short-circuit current
as defined in IEC 60439-1 and the Short-circuit test current by
UL 508C is 100 kA.
Maximum power through common DC connection is equal to the
drive nominal power. See ACS355 Common DC application guide
(3AUA0000070130 [English]).
Approximately 95 to 98% at nominal power level, depending on the
drive size and options.
IP20 (cabinet installation) / UL open: Standard enclosure. The drive
must be installed in a cabinet to fulfil the requirements for shielding
from contact.
IP20 / NEMA 1: Achieved with an option kit (MUL1-R1, MUL1-R3 or
MUL1-R4) including a hood and a connection box.
