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 BW 151

    Braking resistor, max. continous power: 300 W

    BW 156
    • Resistance values: 1,1 - 2000 Ohm
    • Continuous power: 50 - 300 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.



    • protection class IP 20 / IP 54

    • higher protection classes on request

    • test voltage 2.5 kV AC

    • other capacities and mounting dimensions on request

  • REOhm series 156 (UL)

    Max. continous 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).
