Brake resistor connection data
The brake resistor output is conditionally short-circuit proof by
IEC/EN 61800-5-1 and UL 61800-5-1. Short-circuit protec-
tion (IEC 61800-5-1,
IEC 60439-1,
UL 61800-5-1)
Rated conditional short-circuit current is as defined in IEC 60439-1.
Energy efficiency data (ecodesign)
Energy efficiency data according to IEC 61800-9-2 is available from the ecodesign
tool (
https://ecodesign.drivesmotors.abb.com/ ).
Energy efficiency data is not provided for the 1~230 V drives. The drives with one
phase input are not in the scope of the EU ecodesign requirements (Regulation
EU/2019/1781) or the UK ecodesign requirements (Regulation SI 2021 No. 745).
Degrees of protection
IP20 (cabinet installation): Standard enclosure. The drive must be
installed in a cabinet to fulfill the requirements for shielding from
contact. Degree of protection
