UL resistors

REO resistors are UL certified

The independent organisation "Underwriters Laboratories" (UL for short) has developed more than 1,300 safety standards.

Many of these standards are in accordance with the American National Standards (ANSI) and, alongside the requirements for electrical safety for electrical items, they also often take into account additional requirements in relation to flammability.

  • REOhm series 153 (UL)

    Max. continuous power: 360 W

    BW 156
    • Resistance values: 0.26 - 2000 Ohm
    • Continuous power: 100 - 400 W
    • max. operating voltage: 900 V

    The BW 153 braking is designed for drives with frequency converters of small to medium output. The installation is close to the frequency converter.  
    In addition to the high protection class IP66, the profile resistors REOhm 153 are also UL-certified and have a power of 100 W up to 400 W (also as combination).

     Maximum energy with minimum space

    • Unity-version can be assembled as low-profile and upright
    • Suitable for IP 65 applications
    • The REO flat resistor can be screwed under or on
      the side of a frequency drive using a mounting plate
    • In case of failure of resistor, this will become highly resistive
    • Test voltage: 2.5 kV AC (at 900 V rated voltage)

    Optional

    • With temperature switch
    • Cover for protection against high surface temperatures


  • REOhm series 156 (UL)

    Max. continuous power: 1,500 W

    BW 156
    • Resistance values: 0.3 - 2000 Ohm
    • Continuous power: 400 - 7500 W
    • max. operating voltage: 900 V

    The BW 156 braking is designed for drives with frequency converters of small to medium output.  Installation in and outside the control cabinet is possible.
    In addition to the high protection class IP66, the profile resistors REOHM 156 are also UL-certified and have a power of 50 W up to 7,500 W (as combination).

     

    Optional

    • With temperature switch
    • Cover for protection against high surface temperatures


  • REOHM BW 151 (UL)

    Braking resistor, max. continous power: 300 W

    REOHM BW 151 (UL)
    • Resistance values: 10 - 300 Ohm
    • Continuous power: 50 - 250 W
    • max. operating voltage: 900 V

    Braking resistor for drives with frequency converters
    of low to medium power or as a charging resistor.
    Mounting close to the frequency inverter.
