BW series braking resistors
Technical Data
3.10 BW series braking resistors
General informa-
tion
BW series braking resistors are adapted to the MOVITRAC
®
07 series of inverters. The
braking resistors are convection-cooled. The permitted ambient temperature range is -
20 °C ... +45 °C.
Flat type
The flat-type resistors have IP54 enclosure and are equipped with internal thermal over-
load protection. Once an overload has occurred, the resistor must be replaced. You can
install the resistors as follows, depending on their type:
• Push into the heat sink of the inverter and screw tight (only size 0S / 0M / 0L). Resis-
tors mounted in the heat sink do not achieve the specified cdf power.
• Attach to a DIN rail using a touch guard BS.

Wire and grid
resistors
• Perforated sheet cover (IP20) open towards the mounting surface.
• You can apply a higher load to wire and grid resistors for a short time than you can
to flat-type braking resistors.
