Description
Braking resistor for drives with smaller to medium power frequency converters or usable as a charging resistor.
Installation close to the frequency converter.
- IP54 protection class
- Higher protection classes on request
- Test voltage 2.5 kV AC
- Other power ratings and mounting dimensions on request
Advantages
- Easily combinable
- Inherently safe
- Very flat and compact design with open grooves for vertical mounting
- Adaptation to every frequency converter
- Very good heat dissipation, mounting on heat sink possible
- High-impedance in case of overload
- Quick connection
- Also with UL certification
- Optional with temperature switch

In case of destruction, the resistor becomes high-impedance, therefore each series is available with a temperature switch. The specified power values were measured with the resistors positioned horizontally in the air, at a minimum distance of 100mm from the substrate. The power values refer to the standard products with a normal tolerance of +/- 10% at an ambient temperature of 20°C.
