370 Technical data
Brake resistor connection
Short-circuit protection
(IEC 61800-5-1,
IEC 60439-1, UL 508C)
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.
Common DC connection
Maximum power through common DC connection is equal to the
drive nominal power. See ACS355 Common DC application guide
(3AUA0000070130 [English]).
Efficiency
Approximately 95 to 98% at nominal power level, depending on the
drive size and options
Degrees of protection
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.
