General information
{Comment by , : SEW_Elementprodshort}BW braking resistors are adapted to the MOVITRAC® B inverter series. The type of cooling is KS = self-cooling (air ventilation).
The resistor surfaces will get very hot under a load of PN. Make sure that you select an installation site that will accommodate these high temperatures. As a rule, braking resistors are mounted on the control cabinet roof.
Plan for a load derating of 4% per 10 K from an ambient temperature of 45 °C (113 °F). Do not exceed the maximum ambient temperature of 80 °C (176 °F). Note the maximum permissible temperature of other components (e.g. MOVITRAC® B) when installing braking resistors in the control cabinet.
