BW series braking resistors
Technical Data
4.14.3 Flat design
The flat-design resistors have degree of protection IP54 and are equipped with internal
thermal overload protection (cannot be replaced). Depending on their type, you can in-
stall the resistors as follows:
•
With support rail mounting FHS or submounting FKB under the heat sink. The
braking resistors in the submounting do not achieve the specified CDF power. The
FHS and FKB options are only suitable for the BW027-003 and BW072-003 braking
resistors.
•
Attach to a mounting rail using a BS touch guard.
Caution:
The load capacity applies for a horizontal mounting position [2]. Values are re-
duced by 10 % for a vertical mounting position [1].
