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.
Efficiency
Approximately 95 to 98% at nominal power level, depending on the drive size and options
Cooling
Method R0: Natural convection cooling. R1…R4: Internal fan, flow direction from bottom to top.
Free space around the drive See chapter Mechanical installation , page 26 .
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 including a hood and a connection box.
