Braking resistor, max. continuous power: 300 W
Description
Braking resistor for drives with frequency converters of low to medium power or as a charging resistor. Mounting close to the frequency inverter.
- protection class IP 20 / IP 54
- higher protection classes on request
- test voltage 2.5 kV AC
- other capacities and mounting dimensions on request
Advantages
- easily combined
- intrinsically safe
- very flat and compact design with open grooves for vertical mounting
- suitable for the use with any frequency drive
- very good heat dissipation, mounting on heat sink possible
- highly resistive on overload
- quick connection
- also with UL certification
- options available with temperature switches
Typical applications
Braking resistor for drives with low to medium power frequency inverters or can be used as a charging resistor. Mounted close to the frequency inverter.

The resistance values refer to standard products with a standard tolerance of +/- 10 % with an ambient temperature of 20 °C. The resistance value insignificantly changes in function of the winding temperature. Therefore, resistance changes of approx. +10 % in comparison to the cooled-down conditions may occur.
