The brake resistor output is conditionally short-circuit proof by
IEC/EN 61800-5-1 and UL 61800-5-1. For correct fuse selection,
contact your local ABB representative. Rated conditional short-circuit
current as defined in IEC 60439-1.
Approximately 98% at nominal power level.
IP20 (cabinet installation) / UL Open Type: Standard enclosure. The
drive must be installed in a cabinet to fulfill the requirements for
shielding from contact.
UL Open Type. For indoor use only.
